This is not a path towards success since it requires the user to care about
how their connectivity is achieved.

An ipv(v4|v6) decision is only ever made at scale by default, at scale

That said, Android and Microsoft have already included CLAT as part of the
OS.

It would substantially and immediately improve my IPv6 deployment, and
restoration of a proper e2e IPv6 internet,  if Apple would release CLAT as
part of their OS.
