My approach thus far absent CPE support for transition mechanisms has 
been native IPv6 across the board + NAT444, but I use a VRF to 
regionalize the NAT444 routing and bring it to a semi-centralized 
gateway much like one would using DS-Lite, 464XLAT, MAP, LW4o6, etc.

No need to forklift anything, and you can deploy whatever suits you 
incrementally in regions where you need to.  It also works with all 
user-supplied CPE routers which is a bonus as I hate to require that 
users use my CPE router, and it's not yet easy for consumers to verify 
beforehand that the router they're buying at Best Buy will support any 
particular transition tech, though I'd really like to get that fixed.

I'm quite small, though.  I can imagine this would be a hassle compared 
to running a single stack access layer at scale, and of course the NAT 
is stateful no matter what you do with this technique.
