I believe this is implemented now.

This area seems quite messy. Some more comments:

1) inhibit-local-variables-regexps - should it be explicitly
case-insensitive?

2) local-enable-local-variables - a strange variable. AFAICS (see my
comments in files.el), its only real use is as a minor convenience
feature for visiting RMAIL BABYL files with M-x find-file. Should it be
declared obsolete? Should it affect directory-local variables (it
currently does, I think)?

Still to be done after 24.1.
