Of the first two pages of hits, only two relate to GRUB 2; and given
that there's still another instance of "Press any key to continue" in
the code, even those might not be relevant.

Anyway, I really don't think this is at all important given that most of
those hits are not exactly very informative anyway, and we should not
shy away from improving messages just because people have made terrible
attempts to explain what's going on with a previous version of the
message with an open-ended set of causes.

Yes; for instance save_env in a menu item when /boot isn't writeable by
GRUB will do it.

I don't think a countdown is necessary here, so I'm not going to spend
time writing code for it.  But of course you're free to do so ...
