And now pushed to emacs-29.

Looks like time to close this bug (and the merged one). The new user 
option project-vc-extra-root-markers should cover the described use 
cases in both feature requests. The default is nil, though, so people 
will need to customize.

Not every idea from this discussion has made it in, but we can get back 
to them later.
