The protocol is undocumented because the actual messages exchanged are not
public and aren't versioned or managed in a way that would act as an API.
Both halves of the communication are written as a single piece of code
that is communicating with itself, so when it changes, it's changing in
lockstep.

That's also why both halves have to be restarted after an upgrade.

Actually implementing an alternative module in a different web server is
either quite simple if the server API is adequate or impossible if it's
not. It doesn't involve any communication with shibd, that's handled by
the library.
