You do realize that this is contrary to everything we currently do in
Emacs, right?  We should the messages that must be acted upon
immediately, and use sit-for to make sure the user sees the message
and has an opportunity to act upon it.  The message which started this
discussion was just like that: it informed the user that an autosave
file exists, so the user should consider using it.

Maybe so, but this will be an entirely different UX, and probably an
entirely different Emacs.
