Yes, of course you are right that this is a complex issue, but there's a widespread tendency to carry the old limitations of today's IPv4 to IPv6 even if there's no real need to do so. And Marc calling NAT64 a working solution despite the fact that it breaks IPv6 the same way NAT broke IPv4 really asks to be balanced by a similarly oversimplified statement going the other way:-)
Actually, the whole point is that NAT64 does not touch IPv6, so it is not "breaking IPv6" - it ensures that IPv4 legacy is still reachable, even if you're inside an IPv6-only network. Which sounds quite positive to me, given the alternative is "run dual-stack everywhere, forever, because someone out there might still be IPv4-only"... Carriers can't "just turn off IPv4" if users still connect to IPv4-only sites... so what is worse, NAT44/CGN and dual-stack all the way to the client, or nice and shiny IPv6-only at the edges, and NAT64 for talking to the old Internet?
