Really we do not need to be inventing anything new in this space.
We already have too many mechanisms.  ISPs just need to DEPLOY the
existing mechanism.

We have plain dual stack.

We have public IPv4 + 6rd for ISPs where the access network doesn’t
support IPv6.

We have CGN + 6RD + 100.64/10 for ISPs where the access network doesn’t
support IPv6 and they have run out of IPv4 space.

We have DS-Lite, MAP-E, MAP-T, NAT64 … providing IPV4AAS for when the ISP
has run out of IPv4 and the access network supports IPv6.

We have CGN + IPv6.

Do we really need something more at the protocol level?

We do need Governments to ban the selling of new IPv4-only domestic
devices (CPE routers, TV’s, game boxes, etc.).
