The problem is IPv6 Internet is still useless.
It's not a problem. Use port restricted IPv4.
If it will be when IPv4 runs out, the world will NOT be moved to IPv6, but will use NATs, trade the rest of IPv4 blocks and so on. IPv6 will be ignored as working, but useless thing.
IPv6 will be ignored, because IPv6 is, technically, useless, which has nothing to do with IPv6 address allocation policy. Because IPv4 NAT can be fully transparent end to end, it's fine to use port restricted IPv4 with NAT.
I repeat my lovely phrase: If a majority (a half) of web resources will be reachable via IPv6 when IPv4 will be finished, then MAY BE will be the migration to IPv6. If not - then it fails.
It's impossible because attempts of optional headers, path MTU discovery, stateless autoconfiguration, aggressive introduction of multicast etc. to make IPv6 better than IPv4 have totally failed only to make IPv6 and its operation a lot more complex and a lot less consistent than IPv4. Masataka Ohta
