Very good.

Eli, what do you think about this feature 
(project-vc-extra-root-markers) for emacs-29?

This bug has been open a while. I'm not seeing much user feedback now, 
but that's probably because everyone has been living with their own 
custom solution for all this time. And we'll still have time for people 
to report any bugs before the release.

Further, I've done some testing over Tramp, and the new approach 
improves the performance of the default implementation significantly. 
Like with a remote host over 200ms ping, with clear Tramp cache, "cold" 
project-current call is down from 3-6s to 1.9-3.3s (depending on the 
directory depth).

Not sure how many are working over such a slow connection, but that 
could be a nice bump.
