Eliot,

>From a practical point of view we still need to treat the <1024 ports
special. We don't get rid of these systems quickly even if we say: This
was a stupid idea, don't do it, treat them all the same. Thus we need
special assignment rules anyway.

If we want IETF to publish a document, saying this was bad idea. Fine,
but lets not do it in this document. The fix to the service name
registry has been long awaited. Lets try to avoid further delay.
