I don't think this justifies nagging a user who explicitly wants some
file(s) to be treated as using dynamic binding.  The above is just a
recommendation, not a hard requirement.  We are not going to remove
dynamic binding from Emacs, are we?  Then why annoy people who want to
use it, for presumably good reasons?
