Huh? Even in the presense of MTAs in the middle that are free to reorder
messages?

IIRC, "git send-email" does its best to force ordering by assigning
monotonically increasing timestamps on the Date: field, so that the
recipients can sort the messages based on it, in addition to the
In-Reply-To field to help threading. I personally do not think there is
anything more than that that should done in the program.
