FWIW, I don't think this will fly with our users: Emacs users don't
like to be second-guessed, nor be told that "Emacs knows better".  And
even if we do go that way, Emacs is not a black box: people will soon
enough discover what we want to conceal, and will do what they want
regardless.

What we can, and probably should, do is prominently document each test
and warn against removing or weakening those which will expose users
to security vulnerabilities.
