Rather than allowing arbitrary messages, maybe it would make sense to
have a specific feature negotiation message, eg:

VERSION ...
FEATURE wtxidrelay
FEATURE packagerelay
VERACK

with the behaviour being that it's valid only between VERSION and VERACK,
and it takes a length-prefixed-string giving the feature name, optional
additional data, and if the feature name isn't recognised the message
is ignored.

If we were to support a "polite disconnect" feature like Jeremy suggested,
it might be easier to do that for a generic FEATURE message, than
reimplement it for the message proposed by each new feature.

Cheers,
