The NAT64 translation still requires a dual-stack deployment. Of course,
it is a smaller % of your overall single-stack IPv6 network, but still
there nonetheless.

The advantage with NAT64, as you say, is that it easier to rip it out
when the IPv4 Internet dies a happy death, than it would be if one were
keeping IPv4 primary and sticking IPv6 duct tape on top.
