XEmacs 21.5.28 doesn't have it and neither does Emacs 22.2.1 (the
latter from Ubuntu 8.10).

Ugh. I've got Emacs 22.3.1. I'm assuming that's where :safe was first
introduced. I did a quick check and it looks like -*- mode lines are
parsed when enable-local-variables is set to :safe.
Obviously the number one priority is ensuring that parsing works correctly
on all platforms. Could we do a bit of inspection and do a best choice
based on the user's platform. Barring that, how about exposing this so a
knowledgeable user can specify a value if they choose.
