I do not understand the point you are trying to make.

The IETF community usually labels the previous version of a "standard" as "Obsolete" when it publishes a revision of the "standard". RFC 7230, for an example, labelled RFC 2616 as "Obsolete". Some implementations, which were based upon the previous version of the "standard", are still running out there. My web browser has an automated updates feature. The vendor could decide to support non-obsolete "standards" only and switch off TLS v1.2. In theory, six years should be more than enough to get implementations to support the latest "standard". The reality is a bit different.

I read the shepherd writeup. It is dated 4 July 2022. It is somewhat odd that the writeup was written before version -00 of the draft was available.

As one of the TLS experts, and in consultation with the other two, I believe we all understand. IANA will not forward any request for TLS 1.2 codepoints (other than the two exceptions) to the designated experts for review.

There is the following on Page 17 of RFC 8477:

  [IANA] "SHOULD direct all requests for registration to the review
   mailing list"

  "Criteria that SHOULD be applied by the designated experts ..."

  "Within the review period, the designated experts will either approve
   or deny the registration request, communicating this decision to the
   review list and IANA.  Denials SHOULD include an explanation and, if
   applicable, suggestions as to how to make the request successful."

My reading of the above is that:

  1. The service provider (IANA) sends all registration requests to the
     experts.

  2. The designated experts take a decision based the criteria which they
     have been provided.

  3. The designated experts explain why they denied a registration request.

This draft proposes to introduce a step before (1) for the service provider not to forward some registration requests which do not fit the criteria being proposed. Will the service provider also be making suggestions as to how to make the request successful?

The intent is only to show a timetable. If there are no minutes or recording, that doesn't matter. The slides show that a discussion happened and that's the point the draft is making.

Let's assume that your draft were slides. In my opinion, this email exchange would be the discussion. The practice, outside the "standards process", is to have a record which is known as "minutes". I took a quick look at the relevant process document just in case. :-)

If this is really a concern then we can say "first discussion in the IETF community"

I'll say okay to your suggestion.

I don't know, it's hard to get more current than *just last month* :)

:-)

As EKR said, you misunderstand the context. You would have to look through the discussion about the "TLS 1.2 LTS" draft, where it is more clearly evidenced that the WG wants *no changes* to TLS 1.2 other than how it is configured. Many people in that thread missed that the extension point had already been assigned.

Even though I disagree with your points, I do appreciate the very careful read you have to this draft.

I read the "1.2" draft. I noticed that the code point was already assigned. I also noted the point which Eliot was trying to express somewhere on this thread (word used loosely). From what I understand, Independent Submissions provided a path for critiques and discussions of alternatives to IETF protocols to be seen by the communities out there. I don't think that this draft should close that path. The TLS code point requests would still be under IETF policy.
