Ah, we're getting closer.

>I still don't see any use for _tcp/_udp in there.

RFC 6698 has _tcp _udp and _sctp protocols as part of the names for
TLSA.

It seems rather odd to have the protocol name for the server
certificate but not for the client.

R's,
John

PS: In case it's not clear, I'm not proposing that client certs use
port numbers, for reasons that I hope are obvious.
