It means it is 'customer choice' to go IPv6-only, which does not imply nat.
If they see sufficient value to retain the IPv4 connectivity they pay the
price. I suspect many of them will not, which will result in not connecting
to the IPv4-only sites. As long as they have a viable alternative site that
supports IPv6, no nat is required for them to drop their IPv4.
