... maybe the truth is, we've got 15 bits of zero in the header forever, amen.
that's how i treated it when i crafted EDNS0. we'd have to negotiate any new use, and we've since learned that billions of middleboxes will treat that as a 16-bit field which must always be 0 or 1, no matter what the endpoints may have agreed to.
clue-stick hits welcome. Avoid the stomach.
i think that some 30 years before there was an RFC called "pervasive monitoring is an attack" there should have been an RFC called "middle boxes are an attack". forget about killing hitler's grandparents or whatever -- this is what a time machine is needed for.
