For what it is worth, I don't think trying to align the frames makes
any sense, because there is no way we can guarantee that they will
be aligned into underlying TCP and IP packets in the first place.

Things like keeping the :headers first, maybe even in strictly
defined order like HTTP/1.1 does it will be much more important
for high performance implementations.
