notes--

1. i support the adoption and progression of olafur's draft, regardless
of mozilla's retraction of the bad logic in tonight's firefox release.

2. it's not going to change the amplification/reflection problem and
should not mention that problem at all.

3. it should be renamed to "restricting DNS meta-data queries".

4. it should be expanded to include RD=0 against recursion-only servers,
IXFR/AXFR, and anything else in the DNS protocol that would be useful
for both diagnostics and surveillance.

5. non-response to these queries should be designed to avoid re-query
storms from common initiators.

i agree to review and contribute.
