Makes sense.

I really think it's obscure enough that just offerng users a documented
way out should be neough.

I think it's a reasonable feature, but in hindsight our mistake was to
think that we should be perma-forking isync, which has since moved
on. I've used isync's "mbsync" extensively for IMAP in other contexts,
and it works well for that.
So if we were going back to the drawing board a "git-imap-sync" really
should just be something in our mail tooling that can produce a Maildir,
and if we wanted an IMAP helper it could invoke mbsync, offlineimap or
various other "maildir to IMAP" bidirectional syncing utilities to
"send" via IMAP.
So, just some hook support for format-patch with some documented
examples should do it, but I won't be working on that task...
