Owen, do you have any technical objection to raise about this document, or are
you just replying because you like the sound the keys make as you type?
The working group adopted the document, so it's too late to object that the
working group shouldn't be working on it. You can object by pointing out that
it doesn't do what it says it's going to do, but if so you'd need to actually
make the case that it doesn't do that, not just assert that it doesn't do that.
Your point about RFC 2119 language has been addressed, so there's no sense in
re-raising it unless you have some specific objection to state about the way in
which it was addressed ("I'm not satisfied" is not a specific objection).
Etc.
