I stopped my investigations at the point it looked like I needed to edit
notmuch-address.el. I guess another patch or two is needed to do notmuch
integration. And of course we would need tests (in the notmuch test
suite) and documentation before actually merging the functionality, but
those can probably wait until we have a clearer idea what benefits the
change would bring.

The function exists here in Emacs 27.1.

Unless the UX is very close, some people will strongly prefer to stay
with the existing completion, so I guess we'd need to make it
opt-in. Unfortunately as Tomi already pointed out the configuration is
already a bit of a confusing mess.
