And, the NAT44 that 99% of my customer use to today is also a CGN. It's status quo, all v4 flows require state in my network, NAT44 or NAT64. But, NAT64 has an exit strategy. With every new AAAA that comes out, that is one less destination requiring state in my network.
I will give you that it is easy to see with NAT64 when the target space has moved. It also forces you to upgrade all client applications to support IPv6 from the start. Anyway its horses for courses.
