Ok. Will add appropriate text.

Yes, that's most unfortunate. The sedhcpv6 draft was active since 2013.
It went through a total of 25 revisions, multiple discussions,
brainstorm sessions, an interop, a hackathon and even different teams of
authors. Sadly, in the end the WG couldn't agree on the set of problems
that are to be solved, much less how to solve them.
