Well, it's implicitly mentioned in the Renesys blog, for

"Everything checked out for our limited tests. So at least the bogus  
name servers might have been providing the correct responses while  
they were in service, which may be why no one noticed a problem."

And I've mentioned it, and it's been mentioned here, and
it was mentioned on the ICANN blog, and...

If someone changed your resolve.conf file and put a new
resolver in there that you've never seen that may or may
not have been malicious, but no one noticed any type
of "incoherency", then everything is fine?  You might
subscribe to such a thing, I don't.  Then escalate this to
a root level...

Look, you're welcome to ignore this if you want, I don't
choose to.

Yes, I understand what your agenda is, mine is orthogonal,
although they do appear to be related.

I was focused more along the lines of fundamental security for
end users, not burning DNSSEC.
