IMHO, I would say mobile in North America looks pretty much like IPv4
exhaust already happened. All the major service providers have
compromised IP networks in some way.  They all do NAT44 today.  They
use BOGONs and overlapping address spaces, multiple instances of
RFC1918.... that's today.  There are also committed IPv6-only + NAT64
and Gi-Ds-lite deployments being deployed now.

So, there is an IPv4 exhaust model already live and "working".  It can
keep going as is, it does not get easier, but the mobile networks in
North America are not bounding their growth by available IPv4.

Yep, nobody's getting free phones for the purpose IPv6, they just
don't get public IPv4 addresses or end to end connectivity.
