the phrase, "proceeds with the server sending the version it
supports", is to mean that the specification's notion of "accepts"
permits a broker to reply with a Connection.Start with the major and
minor server properties set to reflect the version it supports, but
with no required relation to the requested version, and that standard
practice is to permit just values less than that requested? is the
behavior specific to rabbitmq? universal to all r8.0 brokers?
