No. The expert reviewer can obviously assign a second port in that case (if 
ProtocolX doesn't have a feature negotiation capability built in so that the 
port could be shared.)

But we don't want to allocate multiple ports for the different security flavors 
of *new* protocols. At least we want this to be the exception.

The expert team is (from what I hear) seeing frequent applications that look 
like "Hi, we're company X and our foo protocol runs on TCP. We'd like a port 
for that, and one for when we run foo over TLS."
