Awaiting instructions, but we can certainly do that if there's to be
a new version of the draft.

Ack, the RFC Editor could do that too.

I'd say it is a requirement in order to detect or trace lost prefixes
after outages, and probably a legal requirement in many countries
(once jurisdictions realise that IPv6 prefixes are needed for tracing,
not just addresses). But I agree that it isn't a requirement on the
protocol defined in this draft, so it should be rephrased.
