Interesting.

Do you think we can achieve the goal without changing RA / adding a bit ?

I believe constraining this to 3gpp makes this achievable, as the link does
not even run DAD. Duplicating PD functionality is a feature, not a bug.  As
Joel pointed out, the ietf has already agreed to have 2 approaches for
assign addresses. Adding DNS to RA has been a good thing.

Also there was a question about the router being able to authenticate the

In 3gpp, this is assured by low layer technologies
