In the outliner we don't have yet a clear distinction for the users of when to use each of the visibility settings. I plan to change that by properly naming the property and their tooltips.

Short version == what you see in the RNA API (likely never in the UI)
Long version == tooltip you see when mouse hover the property in outliner

Long version:

• Exclude from view layer
• Temporarily hide in viewport
• Globally disable in viewports
• Globally disable in renders

Short version:

• Exclude from View Layer
• Hide in Viewport
• Disable in Viewports
• Disable in Renders

The API itself does not need to change.

What I will change though is to remove any reference to instance we may still have lingering around.

Note: The order in the menus are different. So I'm also proposing to have the temporary hide before the global one.
