This becomes pretty tricky because Git parses OpenPGP headers in a
variety of places (e.g., at the end of tags).  If your proposal is to
wrap new formats in a fake OpenPGP format, like some existing tools do,
then that would be viable, but otherwise you're going to require either
Git to know about your signing format specifically (which is not a
sustainable approach) or some sort of configuration framework like has
been previously discussed.

If you're going to wrap things in a fake OpenPGP format, then you don't
actually need to send any patches to Git at all; you can simply set
gpg.program and continue.
