This draft has also not, as far as my records show, been adopted as a
DNSEXT item. We did have a previous request for adoption, however.
If you support adopting the draft by the working group, please say so.
If you are willing to work on it (== review it through to completion),
please say so as well. Without at least five committed reviewers, we
can't adopt it, since we won't have enough reviewers committed for
WGLC.
