[Med] Hummm… I suggest you have a quick look at this page : https://datatracker.ietf.org/wg/v6ops/documents/ (hint: search for ‘host’ or ‘CPE’).

The search says that a single-digit percentage of the documents contain the word "host" or "CPE" in the title. What point are you trying to make? That the charter is inappropriate, because it doesn't mention hosts, but the WG has published a few documents that talk about hosts?

[Med] The answer is obvious : the WG has no problem to publish such documents.

In fact, if you look at the numbered list in the charter, the items are "identify operational issues and determine solutions", "identify potential security risks", "identify portions of the specs that can cause operational concerns", and "analyze solutions for deploying IPv6 within network environments". None of those cover this document.

[Med] Is this a joke? Your assertion is erroneous. I will take one item randomly from the I-D to illustrate the first item in your list:

   C_REC#7:  Because of potential operational deficiencies to be
             experienced in some roaming situations, the cellular host
             must be able to be configured with a home PDP-Context
             type(s) and a roaming PDP-Context type(s).

That's a great example to pick, because the WG is about to produce an RFC on precisely this topic - https://datatracker.ietf.org/doc/draft-ietf-v6ops-ipv6-roaming-analysis/ .

[Med] I can inform you this will be published as RFC7445. It happens I’m co-author that document, so I’m not discovering it. Furthermore, this is cited in the mobile profile draft:

                A detailed analysis of roaming failure cases is included
                in [RFC7445].

That document is a good example of what *is* in charter of the WG: an in-depth, detailed discussion of the operational issues. 8 lines of text saying "devices must support different PDP types for home and roaming" is not.

[Med] There is no recommendation in the roaming analysis draft. The profile document includes a clear recommendation on the current plan of most operators to handle the roaming issue. We don’t need hundreds of pages for that.
