I simpatize with some of the comments. That said, temp addresses tend to
be disabled in enterprise environments (for some of the reasons you note
in your I-D)... and when it comes to DoS attacks, in the IPv6 world
you'd fan a whole /64 as opposed to a single /128.

It certainly wasn't the original idea. Then it was an open question. And
now I'd say that we should probably obsolete rfc4941, but of course
that's up to the wg.
