We are not, as far as I know.  I have made my changes without doing
that.

However, this brings up the issue of how a backend will fail if the
client provides a newer protocol version.  I think we should get it to
send back its current protocol version and see if the client responds
with a protocol version we can accept.  I know we don't need it now, but
when we do need to up the protocol version number, we are stuck because
of the older releases that can't cope with this.
