I am currently advocating for a combination of
1. We already do that so have the data
2. Possibly not as the device must already been booted on the net using IPv6, but still a means to handle exceptions.
3. Needs changes to ISC DHCPD, which is sort of where this whole conversation started. ( but my preference ).
4. Same as 2.
5. Not a hope and I am not going to wait for it.
