Could a check box be added to allow users to toggle between Zbrush Behavior (new pinch brush) and Blender classic Behavior (Blender 2.5x to Blender 2.82)?

Many thanks.
I've started all my projects in Blender 2.7x.
When i open my blend files win Blender 2.8x, i don't have the new brushes.
When starting a new scene i have all the new brushes.

No problem if it becomes the default setting but i want to switch back to the previous behavior of pinch brush.
How do i do?
I've been sculpting for years with Blender.
I prefer the good old pinch brush.
Never heard people complaining about it.
I just played with the lock axis to get the same result.
For me, the new brush is too similar with the crease brush.
The old Pinch brush was excellent to correct scale/proportion problems.

Start a new scene.
Select default cube.
Enter sculpt mode.
Enable dyntopo.
Add details randomly with draw brush (just to have vertices to play with).
Use Pinch brush: the brush will not affect z axis.
