And here is the discussion behind these commits:

  https://lists.gnu.org/r/emacs-pretest-bug/2007-03/msg00267.html

I was not able to find out why the commit that removed the 'safe'
property from `default-directory' had been reverted, though.  Let's
assume that it's not trivial.

Maybe it would be "safer" if a file local binding of `default-directory'
would only be considered as safe if that directory is not something on a
different machine?

OTOH, (info "(elisp) File Local Variables")

So... I dunno.
