The problem is that No NAT for IPv6 is religious dogma, regardless of 
the reason anyone may have for wanting it, which may have nothing at all 
to do with address sharing. Even fixing multihoming and readdressing (to 
the extent it may be possible) will not eliminate any and all 
motivations for NAT. Its time to standardize NAT and move on.

Now imagine if all those CGNAT boxes are also doing a workable version 
of NAT-PT. Deploying customers with any IPv4 becomes optional.
