Hi Vincent and list,
first I wish a happy new year to you
and hope for individual health and general more peace in the world!

I also do not know what is going on.
My response mainly aims to explain that the way a question is asked
already makes assumptions. And if we want to reach collaboration
we need a respectful way of treating each other.

Given the cited charter and way the "design team" works in followup
to your post, the design team was a closed process.
And according to Werner the design team was in consensus and on a good course,
with only details to sort out, until he had to leave it.
So we need to find out what was happening in the IETF WG design team (often
abbreviated DT) after this.

Thanks for providing a link to the mail archive showing one part
of the process that is on public record. After reading a few mails
my current understanding is:
* There are overlapping (and partly conflicting) drafts,
let us call them "koch" and "newdesignteam"
* The "newdesignteam" draft is much longer and more complex
(at least according to Peter Gutmann and Werner Koch)
* The "koch" draft is implemented widely (which was common practice
to test the specfication).
* Somewhere the closed DT deviated from a consensus that the previous
"koch" drafts had in the working group and of the course the DT had
in their closed group.

As you wrote mails to the WG list, you will have seen what Werner already
wrote about is a good path forward for the existing implementation RNP and

[..] We deployed things years ago
and won't extend that unless there are sound reasons for it.
It would be a bit sad if we eventually need to state: "GnuPG implements
OpenPGP as specified by RFC-4880 and RFC-6337 plus some extensions
described [[here]]". However, our users and their data is more
important to us than implementing a newer RFC.

[about newdesignteam draft] a brief reading shows
that it way to complex for an update of OpenPGP.
I have not read the new v5 things in detail but I can imagine
that we can still change the format. We have been cautious enough to
tell people that v5 has not yet been finished.
It seems after this, not much has changed on the "newdesignteam" draft.

GnuPG won't follow the likely outcome of the IETF OpenPGP WG because we
value our users and feel a responsibility to keep a deployed and
sensible moving ecosystem alive and working.
So yes, it seems that the outcome of the WG is an incompatibility.
And the stated plan of GnuPG seems to not follow the WG outcome,
until it changed to be less complex and more towards the early consensus
points. (The 10th of October 12:34 mail shows some technicals where
both sides seems to be open.)
It would be good to have a more official statement from GnuPG
and RNP about this. At least I'll go asking.
But I also think that others need to dig through the data so we get
a summary about the technical issues and the reasoning.
And also ask questions about the rational of the remaining
closed design team.
