Why not leave alone that additional PREDICATE argument of list-buffers-noselect, and add a feature where the BUFFER-LIST argument could be a function? That's be a compatible change. Just keep the PREDICATE argument and the code which supports it, and document that if PREDICATE is a function, BUFFER-LIST cannot be a function.
While that should work, that change would *also* change the signature. Though in a safer way, yes.
Are you worried about some out-of-tree clients that started using the new feature in the meantime?
Otherwise, this change could be split into two steps:- Rollback that signature to pre-commit 125b5684c (i.e. revert its part in buff-menu.el). This is something we usually considered to be safe.
- Add new change that allows BUFFER-LIST to be a function.
