I agree with most comments from Jinmei, but here's one which requires 
a comment..

I personally don't think having a router which doesn't have any DNS
servers configured is a very feasible scenario.  All the routers I can
quickly think of have a configured DNS server.

But I think what you're saying in the second paragraph is slightly
different. I.e., today's low-end router/NAT boxes have DNS servers,
but those are configured using DHCPv4.  How would DNS servers be
configured on such boxes when they support v6?  This is probably a 
good question.

Note that in some environments, this may not be a problem (e.g., 3GPP)
-- where you can assume that the first-hop router is a real, manually
configured router, not a low-end CPE.
