Not only you -- I do agree thoroughly. The hard part is that most of
Emacs isn't aware that things can happen behind their respective backs.

Providing the low level mechanism is just putting the can opener to
Pandora's box: dealing with what comes out is definitely the more
interesting part :-)

(Don't get me wrong: the metaphor I used might imply I don't think it's
desirable. Quite on the contrary).
