Thanks for the pointer—I wasn’t aware of these functions. (I’m still on 28.2.)
It looks like these do fit the bill. For example, it looks like I could write:
(match-buffers condition (project-buffers project))
I can’t see these functions in my local installation of compat (056e3cc), but
maybe definitions from Emacs 29 haven’t been added yet? In any case, I’m happy
to wait a little bit.

Given the functions you mentioned, I think it’s probably not a high priority to
solve the problem in project.el.
Thanks!
