I think that the majority of the major DISCUSS (Alissa, Eric, and Rob)
and general feedback/comments have been addressed by the change in
status/removal of the pseudo-2119 language. However, the document will
(of course) undergo another full IESG Eval, and so all of the ADs will
have another opportunity to review the document and
confirm/double-check that their comments and concerns have been fully

In particular, Erik had a DISCUSSS unrelated to the Informational/BCP
question, and so I've asked him to work with the author to ensure that
his comments have been fully addressed -- it would be stupid to do
another IETF Eval which results in the same DISCUSS position...

I believe that this document is getting more review than most - it is
having 2 WGLCs, 2 IETF LCs, and 2 IESG Evals; if comments are not
addressed when I take to the the second eval, I expect my co-ADs to
point out (loudly!) that their comments are still open...

The computing scientist’s main challenge is not to get confused by the
complexities of his own making.
