Cool, this is getting nice and simple.
It seems like we're ending up with a "NoiseSocket" (or whatever) that just adds a simple negotiation and padding framework, where a higher-layer protocol is going to fill these in by choosing:
* Encoding for payloads and negotiation_data (eg protobufs)
* Noise patterns (eg XX)
* Versioning (eg maxVersion+minVersion; different enumerated fields; centralized registry versus application-specific)
* Authentication (e.g. certificates)
I wonder if the NoiseSocket API should also be more generic? E.g., maybe it should just use functions like ReadHandshakeMessage / WriteHandshakeMessage. It would be for the higher-layer protocol and API to assign more specific meanings (ClientHello, ServerAuth, ClientAuth)?
