>    Not true.  I put forth proposals almost 2 years ago, and the WG refused

Perhaps "did not want to work on them" might be a less emotionally-charged way to say it.  But I understand your frustration as you have been working on network time for a very long time.  (Believe me, I can relate -- wanna hear about my arguments with OpenSSL? :)

Because the WG hasn’t been interested, and because the WG really "owns" the port, its semantics, and the associated registries, you might need to find another way to convince the WG. One possibility might be to carve out a "private" numbering space and -- this is the key, I think, compared to previous efforts -- *not* try to take whole classes of numbering.  Go for it onesie-twosie as you've documented and/or implemented things.

>    We will implement and document what we propose soon.
  
Great.  Until then, there's nothing for the WG to do, right?  And you can't carve off large portions of "land" if the WG has already expressed lack of interest.

As for sharing 123/TCP with NTS-KE, your protocols can use TLS ALPN just like NTS-KE is doing.  The requirement to get an ALPN identifier is low: an internet-draft (even if individual) suffices. If you're doing plaintext over 123/TCP on the public Internet, then please think again.
