At first glance this looks very useful, as an optional hook rather
than on by default[1].

It sounds like a good use for hooks.

Receiving side: an update hook should do the trick.  See the githooks
manual page, or /usr/share/doc/git/contrib/hooks/update-paranoid for
an example.

Sending side: there is no pre-push hook yet, but there was some work
towards that about a year and a half ago[2].  Maybe someone interested
could revive the topic or figure out what remains to be done.
