> Currently when a proxy is created for a protocol, there is a round trip of messages to
check the protocol version. The protocol version is not checked in any subsequent rpc which
could be a problem if the server restarts with a new protocol version. This issue and also
the additional round-trip at proxy creation can be avoided if we add the protocol version
in every rpc, and server checks the protocol version for every call.
