And it will not be, as long as
* (S|D)NAT are not first class citizen in IPV6 Standards and Implementation * there's no mapping of the IPv4 Adresspace into the v6 space, so people can reroute stuff which is needed.
because only then, we can a) migrate b) rebuild the same structures.
because people will never let go of something.

Yeah, I mostly agree... IMO, a ULA (equivalent to RFC1918, so 192.168.x.x and so forth) is the only sane way to set up your IPv6 network at home, unless you're one of the wizards who owns their own prefix. Dynamic prefix delegation just breaks too many things when the prefix changes, and I really wish NPTv6 was more supported and ubiquitous, because it solves the problem in the most elegant way IMO.

Uh, what? What do you think ::ffff:1.2.3.4 is?
