My ISP back in January remotely updated the 3 year old consumer router to support IPv6, however they have not issued any addresses to it yet. I am impressed that an ISP is taking responsibility for the router. The issues with security and bufferbloat/latency mean that these devices can no longer just be left with out-of-date version of software, ISPs need to help consumers with this vital part of the Internet infrastructure.
The same is possible for the home or office networks, but so far I don't have native IPv6 at home, which I think would makes it kind of a kludge to implement. So I haven't done it.
I think MAP for IPv6/IPv4 is also a great idea, because it too is stateless:
There are people doing really interesting things with IPv6 as a first citizen or IPv6-only solutions:
