Protocol version is one thing and should be defined by the RFC.  All
implementations of the protocol should advertise the same version.

Software type/version of the implementation is something else.


Yes, everything may be from nut sources, but having a protocol RFC is
about moving from "the protocol is defined by the code" to "the protocol
is defined by the spec".
