If you like. No recursive option seems also okay.

FWIW, speaking of Tramp, we can either avoid cleaning remote dirs, or at 
least make sure the connection is on before checking (and skip those 
where it is not).

And another way to limit the performance impact is to cap the number of 
projects in history.

kill-emacs-hook is also a good place to use it indeed. Maybe we don't 
need the other hook.
