Now, I CAN unterstand your intention exactly.
Where can we discuss new protocol extensions if neither in IPv6 wg, nor in DNSOP wg?
This is a question for all DNSOP members except for you.

If DHCPv6-lite is a subnet of DHCPv6, there may be no problem that RA-based DNS Discovery
coexists with DHCPv6 like in ND spec.
A significant number of people, including me, really want RA-based DNS Discovery.
I think, they know the usefulness and operation of DHCPv6.
At least my company has implemented DHCPv6 client/server fully.

I think, I did my best to appeal the necessity of RA-based DNS Discovery, 
although I could not express my opinions well enough because of the limitation of Non-English speaker.

If there is proper reason RA-based DNS Discovery SHOULD NOT coexist with DHCPv6,
I will also rescind my concerns about RA-based DNS Discovery.
Thanks.
