Paul, as you must know, this whole area has been extremely
controversial, with a regular pattern of people citing documents
as supporting things that their authors didn't intend and
reading and stretching language that was intended to be clear as
ambiguous. So, the first part of the answer is that, if someone
thinks the current text is unclear, it makes it clear. To do
that, the draft needs to offer an authoritative interpretation,
not an author's point of view, and that can be done only with a
standards track document that updates the base standards
(remembering, too, that the IESG has taken the position that
simply putting "updates NNNN" in the upper left of a document
requires that the new document be standards track if the old one
Would it help if that sentence said "in the opinion of the
authors and those authors of RFC 5891-5893 who were polled, it
does not alter..."? I'd hate to clutter the abstract (which is
already pushing length limits) with that level of detail, but I
imagine I could track down the relevant authors and get their
consent and put something to that effect in the document body.
Suggestions as to then how to tune the abstract text would be

See above and my note about why I don't want to open the entire
box/ can of worms.

I have never intended that it be discussed on a private mailing
list and have written Alexey asking how he wants to handle it
and where he wanted it discussed (and, btw, suggesting that, if
the answer was this one, that it be moved to IETF equipment).
I apologize for not realizing I hadn't done that until this
weekend, but I do expect to fix it in -01, which I will get
posted as soon after I hear from him as possible. In the
interim, this is not a "private mailing list", it is the mailing
list from an IETF WG that has closed, a perfectly orderly place
to have this type of discussion.
