I'm happy with the new Applicability section. However, there is an editing
problem with the first sentence of its final paragraph (some words need to
be deleted, I suspect).

IMHO, since this does not formally update a 6man document, I don't think
it's required to be processed by 6man - but a special WGLC in 6man would be
reasonable in any case, to avoid unexpected issues at IETF Last Call.
However, that's only one person's opinion.

Since 6man is not meeting in Toronto, please let us know if the draft
will be discussed elsewhere.
