In the context of the 6renum WG, that is a very important point.
We need to figure out the best way to automate the DNS
consequences of adding a new IPv6 prefix, or removing an old
one, in all or part of an enterprise network. So we need to
understand how it interacts with DHCPv6. Basically I think
you're saying that in real life we can't expect end hosts to be
responsible for their own DNS updates when renumbered, because
that requires an unreasonable key distribution mechanism.
