More testing is welcome.

It all depends on what's in project-find-functions. With project-vc it 
will probably work as expected (module the problem that was brought up 
in bug#59722, but we'll need to fix that separately anyway), but it can 
behave unexpectedly with more complex project-finding logic, like the 
one favored by Stephen L. or Eli Z., where belonging to a project is not 
defined by the directory only. But possibly by the major mode as well.

And I'm guessing project-buffer-name-function will usually be called 
before the major mode is set.
