We can listen on both ports.  (4 if you count IPv6)  I think that avoids a 
flag day.

It might be possible to avoid a flag day on the extension numbers.  The idea 
is to accept either set, remember which arrived and use those for the reply.  
That's just complicated/ugly enough that I think I'd prefer a flag day.
