It's only in the sources, sorry.

Unless we broke anything accidently we should still be compatible with
0.9.0, which is quite old.

Note that the protocol is kinda complex, both because it grew
historically and because some parts have to be complex. i.e. the
timing/flow control logic is non-trivial. Reimplementing that won't be
fun.

tbh I don't think the native protocol while it works quite well these
days is something that deserves to be reimplemented by other projects.
