Just one note here: the tag order matters a little, the signature
of from the sender should take the last place.

I also believe, as suggested, that we should seek an ack from the
maintainers here. Maybe we could have CC'ed just for this single

to pollute the commit log. This way you let git-send-email handle
it).

Nevertheless, same as I agreed earlier:
