Why can't you run dual stack with CGN?
This takes you [1] down a path which goes against architectural
assumptions. A CGN creates fractions of the addressing space. As
the addressing space per customer diminishes the Internet service
vendor will have to reduce the level of access sold to the customer.

It's not that people want CGNs around for a long time. It's an
irrational choice [2] as people might feel that they are wasting what
they have paid for.
