Yeah, maybe. Otherwise, all that logic is not only implicitly part of
the protocol, but essentially impossible to change because it'll be
hard-coded into clients. I wasn't too worried about this before because
I supposed that only walsender and walreceiver really needed to know
anything about it. If Magnus is busy coding something else that speaks
that protocol, we have a problem. (Assuming we believe his use-case is
sane, that is.)
