I find NBSP to be a source of too many problems, so I think it should be
kept for those rare cases where the unbreakability of a space isn't obvious
from context.

Try (add-hook 'fill-nobreak-predicate 'fill-french-nobreak-p)
Note that fill-french-nobreak-p is new in Emacs-CVS.

Indeed, it's messy.
