Upon re-reading what I wrote I realize that my statement was
misleading. I meant to say that the JSON keys "init_ssk" and "resp_ssk"
are applicable (if defined) to all handshake patterns always and
everywhere. In other words, there is no rule which states, "SSKs apply
to all handshake patterns /except/ XX and NN because foobar". This is
what I mean when I say, "generalizes to all handshake patterns".

It's precisely this generalization which keeps the resulting code
concise and readable.

I've always interpreted Noise Pipes as being a higher level feature
whose semantics are defined by the application, not by the Noise
library.
