I agree here but this means we should keep at least one well-known
port, 53.
 
IANA should be told to close the well known ports
registry. Applications should use DNS SRV records for service
location.

I agree with that rule for the *future* protocols. But it does not
help with current (and widely deployed) protocols. So, asking IANA to
refuse new registrations in the well-known ports registry is one
thing, shutting down the registry is another.
