BTW, and on a tangent, a derived dir-locals-mode isn't the

maybe impractical for other reasons and not justified by this case.

The lisp-mode-variables function does that job, more or less.

So one can just copy the emacs-lisp-mode definition, rename it to dir-local-mode and remove the unnecessary stuff (which will be at least a half of its definition).
