Yeah, I'm totally with you.

I've been thinking of this as a separate document (maybe "NoiseLink"?)
on top of NoiseSocket, that defines how the client can offer a list of
named protocols that the server selects from.  Perhaps defined
abstractly enough that we could instantiate it with protobufs, JSON,
or others.

I need to just start this document so we can critique it, will try soon...
