Makes sense to me - and has the important feature of NOT affecting 
any existing IPv4 only clients. If you start changing the existing 
protocol then you either have to duplicate options - ie an option 6 
plus a new "option 6-4 plus 6-6" - or you break all existing clients !


What's needed IMO is clients to think about how to manage multiple 
sources of DNS server info (which is already an issue in a multihomed 
IPv4 environment).

One option of course would be for the IPv4 client to manage only IPv4 
nameserver settings, and the IPv6 client to only manage IPv6 
nameserver options. What to do if the two disagree on what the domain 
name or search order should be is "difficult" whatever you do :-(
