Re: [DNSOP] Adam Roach's No Objection on draft-ietf-dnsop-serve-stale-09: (with COMMENT)

Thank you very much for your review, Adam.  I have incorporated your
feedback into the document (which is not yet pushed to datatracker).

Here's the diff:

I definitely agree it is questionable, and if something needs to be
done to resolve this then your first suggestion is the one that is
more agreeable to me personally, but I can also see how that too is
questionable and might get some pushback.  It's a bit of a weird
situation. 

It is perhaps worth noting that several other RFCs that have updated
1035, starting with 3658, have already used 2119 normative keywords.
So in spirit it's already there, just not with an explicit remark in
any of the that formally puts the boilerplate on 1035 itself.  (And,
in the end, that means 1035 is a weird hodge-podge of old world and new.)

Completely agree, except to the point that if it were known that there
was money riding on it then someone at a CA would read it just to take
your money. :)  That said, anyone have thoughts on how best to bring
it to their attention?
