Surely the case is that you've still got the same number of users who need an
IPv4 address to be able to access "legacy" IPv4 sites on the Internet - until
100% of content is accessible via IPv6.

What it does, however, change is the amount of traffic which would need to 
flow through a CGN box.

Unfortunately, CGN is here until either everything is available over IPv6, or
a better version of NAT64 which doesn't depend on DNS rewriting is designed
and deployed.
