Ron,
The normal typography is 6to4, not 6-to-4. I assume the draft will
still refer to [I-D.ietf-v6ops-6to4-advisory]. Given that, I believe
the draft should proceed.
I definitely disagree with those who say this would be a misuse of
"Historic"; the words in RFC 2026 certainly cover this case
("for any other reason considered to be obsolete").
Regards
Brian Carpenter
