Just had an offline conversation with Paul and Kunal. The agreement is that
we should introduce a versioning mechanism at the protocol level so that
clients could advertise their version identifier; this way the server can use
this information to turn on / off features based on the client capabilities.
The task is only to create the preliminary versioning infrastructure; more
sophistication can be added later on.
