I agree that the status of the RFC has no immediate or direct
impact on the real world. But I think it's orthogonal to the
*operational* question of how to eliminate the residual A6
records and how to eventually eliminate A6 queries. Mark is
completely correct that this would require a plan - but since
it's a purely operational matter, presumably it belongs in DNSOP
if it belongs anywhere in the IETF.

Marking the RFC as Historic would only be the first step,
apparently.
