Sorry for the noise but when you said

and to start organizing everything better.

What do you have in mind, the sentence sounds empty and notice that there are people who are really shortcuts-oriented. Wouldn't be better to start a task and we discuss about this?

Since Editing Face Sets is not the most essential of tools it can be left to the user to define a shortcut for the Tool for quick access but I wouldn't mind if Ctrl W would still be reserved for the Edit Face Set Tool by default.

Both Ctrl W and Ctrl Alt W were introduced before having the edit face set tool, so back them there was no other way or executing these operations. The new expand operator supports resizing existing fee sets interactively, so I don't see a reason to keep these.

I think this could be handled in another patch to replace the current shortcuts with improved ones. Pressing Ctrl + a number is not the most convenient way of switching multires levels and I won't miss it personally but we should bring up the discussion on D7560 again (on blender chat, not here) to get a final design to overhaul how we use the multires layer switching,

Going up and down one level is still available, which is the most common way of switching levels. Also, this keymap entry will create the subdivision without warning (unlike that operator in the patch). That means that if you press Ctrl + 5 instead of Ctrl + R by accident is an instant crash. Instead of keeping this, we can create a follow up patch to this on moving the level up and level down shortcuts to a more accesible shortcut.

Box mask should ideally still stay until we create a proper design on how to make the most used gesture tools more accessible.

I don't see a reason to just keep box mask if we are cleaning up the keymap. I don't see it as a particularly useful operation over any other gesture (I would rather have line or box reshape as a shortcut over box mask). I would rather leave it for later until we have a more consistent way of creating shortcuts for the gestures.

I'm against these changes since these shortcuts are actually very useful for a dyntopo sculpting workflow

Shift D can stay, but I don't find a shortcut to toggle dyntopo on/off useful at all. That is a destructive operation and when working with high poly meshes, it can easily crash Blender. I don't see a workflow reason to keep toggling Dyntopo on and off so often that you need a shortcut for it.

This is the actual controversial part of the patch. I think except for the Mask, Crease & Inflate brushes this is completely the right way to go.

Personally, the only shortcut I use is G for grab. The other brushes I use the most (elastic deform, pose, boundary) don't even have a shortcut. Even if it goes against my workflow, I think we should try to avoid shipping Blender with any brush shortcut by default, because that should be the role of the brush management system, not the keymap editor.
We can keep the brushes you mentioned just to keep the same workflow speed we are used to, but we need to keep in mind that this is just a hack until we have brush management when designing the rest of the sculpt mode keymap. We were doing a similar thing with the toolbar, using it as a replacement for the brush palette of brush management, making the problem worse for the future.

What I'd love most is more consistency between Sculpt Mode shortcuts and other areas of Blender. For example, Shift + R = Repeat last everywhere, except in Sculpt Mode, because it's assigned to voxel remesh resolution.

Also, primary functions should have direct keys, not Shift + key. For example, I often switch to the Smooth brush to change settings for smoothing, and 'S' has always been Smooth, until it was recently changed to Shift + S.

Next to always turning back the Smooth brush shortcut to 'S', I also revert it to the old toggle behaviour, so you can easily press 'S' to go to the Smooth brush, change some settings, then press 'S' again to return to your previous brush.

@Metin Seven (MetinSeven) Good points. The plan is currently that S is reserved for the color picker, just like in the other painting modes. This will get implemented the moment Sculpt Vertex Color will no longer be an experimental feature.

It is relatively pointless to clean up sculpting keymap in the name of "organizing everything better" without tackling the entire insanity of Blender's keymap overall. If the sculpting portion of the keymap really ended up truly better after this, it would also mean it would be significantly inconsistent with poor key mapping in all the other areas of Blender.

Better organization is simply impossible if it's not tackled Blender-wide. Otherwise either:
A, It won't be really better, just different, but not better.
B, It will require users to switch muscle memory even between individual edit modes of a single piece of software - Blender.

I would definitely restore these hotkeys that was removed:

• M = mask brush
• C = Clay brush

I personally don't have a lot of strong feelings regarding the hotkeys, but I know that there is a huge amount of users that uses clay and mask often.

This was my fear, when I was reading the title of thread. My big question is how can you provide a keymap that will suit everybody? the answer is simple, it is impossible. So this thread is suggesting keymap for everybody that will be made base on 2 or 3 users, you can do that if you want to but what if you change something later, and change again later?
The Blender keymap system is not really user friendly, there is not an user-friendly way to tell the user that there is a shortcut conflict or shortcut is taken, and i think, don't quote on this, that there are still some hardcoded shortcuts. If you do RMB -> assign shortcut, this feature does not exist in many tools e.g. Dyntopo's detail size, stroke method, ... And when new features have pie-menu, the old ones still have small pop-up menu, ...

Blender keymap system need a some love guys.
