And to be clear, the problem with that way of doing it is that the
client has no way to know reliably whether or not to expect
SSH_EXT_INFO, and in particular, to know it *before* deciding what to
put in its SERVICE_REQUEST.

I think it's desirable to be able to know whether or not the peer is
going to send SSH_EXT_INFO, even if I don't agree at all with your
dislike for SERVICE_REQUEST.

One scenario where it matters, is if we define an extension that lists
which services the server is offering.

I wouldn't put it that way. I'd say that we should strive for consensus,
and it's pretty important that that our consensus includes the openssh
folks.
