Exactly. That is what I meant by "Grouping", and I agree with you
about "potentially" part, too ;-) Throwing all @gmail.com addresses
into a single bin would not be very useful.

Another line of thought is perhaps it is potentially useful to teach
the --format= machinery to be a bit more programmable, e.g. allowing
to compute a substring of an existing field %{%aE#*@} without having
to waste a letter each for the local part and domain part. But as I
already said, we are now talking about "postprocessing", and adding
complexity to our codebase only to have incomplete flexibility may
not be worth it. A more specific %(authoremail:localpart) and its
domain counterpart may be easier to explain and understand.
In any case, it is a bit too late to say "let's not waste the
precious single letter namespace to add useless features", as we
have come way too far, so I do not mind too much using a currently
unused letter $X for yet another author and committer trait.
