Isn't CGnat due to IPv6 use on the mobiles? You could quit and say that's an IPv6 problem that didn't get solved in the IPv6 engineering

IPv6 is used on mobile networks since there aren't enough IPv4 addresses. Some of these mobile networks are so big there aren't even enough private IPv4 addresses for their CG-NAT private side to fit, leaving the only clean solution being NAT64/DNS64.

Why would CGNAT be deployed as a response to IPv6 on mobile? I don't understand the logic there. CGNAT is deployed due to a shortage of publicly routable IPv4 addresses. IPv6 was introduced due to having much larger publicly routable space.
