You might consider including such guidance around the SHOULD, if it's not
there already in some form.

You're the author, not the shepherd or the co-chair.  :-)  The concern I'm
raising here is that such a long time between the writeup and IESG
Evaluation forces me to wonder how stale the writeup's content is.  We,
collectively, should get in the habit of checking on this sort of detail
before it hits IESG Evaluation.
