I've missed the rest of the thread and don't have time to catch up right
now.  But AFAIR, one can set flymake-diagnostic-functions in file-local
variables.  So a .dir-locals.el file could have comment  trailer with its
own file-local variables.  If that's too meta, or too complicated, then
dir-locals-mode sounds pretty good to me too.

Actually it sounds better, because it's not exactly an emacs-lisp file,
you can't load or compile it, for one.

I don't know who proposed it, or what it meant exactly, but solving this
in Flymake directly sounds like hack.
