Oh wow, I did not see this feature coming! Really cool! 
It adds another layer to the admin experience.
I tested it for a few minutes. It works great! It’s super convenient.

The visible focus looks weird:
The transition on the button background makes fast changes a bit trippy and gives a sense of flickering.
