Alpha on Viewport Display missing in Blender 3.5.0 alpha version

Can you tell me what happened with this feature in Blender 3.5.0 alpha version?
For what reason? I suppose these changes come for a good reason.
old versions:

The feature is still there, the field has been merged with the checkbox to form a single line. Try scrubbing the field where it is written “0.500”.
I assume the reason of this change is because the alpha value only makes sense if you enable the checkbox, so they are displayed in a single row in the interface.
