It's a universal truth, path of least cost (just see what happens
with routing if you mess with that). However bizarre CGNAT may seem,
it's a hard sell that people should pay more for their Internet so
that their traffic can travel by way of a better protocol; especially
if the introduction of that better protocol is guaranteed to cause
disruption and upheaval.

My research suggests, and I wouldn't mind being rubbished,

is a significant impediment to its adoption.
There's a lot of IPv6 in consumer hands already. Not enough, not as much
as Paul would like, but it is there and it is being used.
Ruminating on the decisions of the past is no more useful than setting
hard deadlines by which we should switch over, and I'm so very tired of
both the cynical and flippant commentary to that end.
In respect of the point that the path of least resistance (or cost) is
your winning technology, then I shall re-iterate what I said on camera
just recently; IPv6 is already your cheapest version of IP to deploy.
- CGNAT equipment costs money in equipment, power, and cooling
- IPv4 addresses cost money to lease or to acquire, - or -
- ... you're giving a $50 IP to commodity subscribers, gratis
There are still some of us that believe this isn't all pointless, and
we're still working on closing the gaps. Migrating slowly isn't a failure.
Yes, we'll need a VERY long tail of compatibility for IPv4-only devices,
and maybe even some standards for 'legacy device zones' in CPE, not
unlike supporting GSM-only devices, or Fax services on the PSTN.
The one thing we need to collectively remember is that it isn't a futile
effort; the work is still happening, and that work needs to be finished
to a point yet determined. Please contribute constructively.
Paul asked a really good question of the community, and we should get
back to helping him with some recommendations.
