I think so, too. At least, it captured mine :-)

Yes. We cannot use a registry because the number of possible methods
is high, and changing, and each method has parameters. So, the idea of
the URL seems OK.

Yes. Otherwise, you cannot survey if draft-vixie-dnsext-dns0x20 is
used ot not.

Is it even possible? RFC 6891 does not mention it. But it says
"OPTION-DATA. MUST be treated as a bit field." which seems to imply
that storing the entire OPT RR, or the option data, as a blob, is
perfectly OK.

I agree. We waited for this document long enough.

Isn't it clearer to say "the last two rules"? "The second two rules"
(meaning the third and the fourth) confused me.
