Not yet, but it seems to have support to move forward. As you say, the big test is whether ISC implements it. Based on the author list, I'm guessing Cisco will.

Ah, NAV, yes we use that along with some other customised stuff. The NAV support team is very good; they've just taken on a full-time developer to push it forward, so may be even more amenable to new feature requests now.
I understand Cisco are working on something too, based on a discussion a couple of IETFs ago.
I just feel in a campus environment expecting to lock everything down to DHCPv6 is not realistic; hence, if you want accountability, you need to deploy harvesting/monitoring tools that do that job for you.
