Things actually slowing down residential IPv6 deployment:
+ Lack of CPE support
+ Lack of Head-End (PON concentrator, DSLAM, CMTS, etc.) support
+ Lack of support from the ISP
One only need look at the free.fr deployment to see that consumers are
actually embracing IPv6 when it is readily available to them without NAT.

Having actually transitioned to dual stack without NAT (in either stack) and
without any security issues resulting from that fact, I'm perfectly willing to
say that I do not believe you because I have experience otherwise.
