Here are my thoughts, with chair hat on.

It's an Informational document (i.e. not Standards Track or BCP).  It
does have some advice about how not to break ECN, but it's not
altering or changing any previous standards or BCPs about how devices,
hosts, or applications behave.

I think it correctly avoids using the 2119 capitalized words (SHOULD,
MUST, etc.).  There are some non-capitalized "must" and "should" words
in section 5 when going through the high-level list of prerequisites
for successful use of ECN, and in my opinion, this is one of the more
useful parts of the document to summarize and bring the advice together.

There's definitely a valid criticism that it isn't particularly
specific about some details in this guidance, but I think that's
probably desirable, as some are still being worked out, and would
ultimately go into Standards Track and BCP documents from TSVWG or
some other working group.

I think as the AQM working group, the level of detail and strength
of recommendations made in -04 are pretty much on the mark for what
we should say.

Certainly people should let us know during this Last Call if they
feel otherwise.  It can be something we explicitly ask the AD to
confirm during their review too.
