How is it disingenuous? I've agreed that it's of interest to a community
which has a process inside the W3C to address their needs. It seems as
though we have a happy co-incidence of wants and processes
to accommodate them at this point. The HTML WG seems to have this in hand.

ISTM that the question of REC or NOTE isn't even a discussion for us to
have; it's up for a vote whenever the HTML WG decides to publish and
request that status change.

The only question that seems to be in front of this group today is: should
the TAG maintain an outstanding request for the HTML WG to produce this

To that question, there's no scheduled TAG work in this area, nothing we
would do to affect the REC vs. NOTE vote (unless I misunderstand the
process or feeling in the room, which is more than possible), and no value
to the TAG in being seen to be asking for a document we cannot cite a
strong need for (or agree a need for). Why, then, are we continuing to ask
for this?
