Perhaps a better lithmus test would be:
"Would an end-user notice if IPv6 was removed from his/her/it's host?"
this would not be the only important test. Another would be: if ipv6
were removed from the entire user base, would the operator notice, and
if it were bad enough, would the end user notice - e.g. pricing,
video-provider dropping out due to NAT session concurrency problems, CGN
hardware/software total-cost-of-ownership, etc.
ipv4 will not go away until there is a compelling reason to abandon it
in favour of ipv6 or another future protocol.
That's always been the plan. Coexistence was always the design target.

One reason to sit up and
take notice is that ipv4 addresses currently cost $50/each, so if you
need lots of ipv4 addresses, they are now a commodity which may make a
difference to your bottom line.
Conversely there are plenty of organisations in some parts of the world
that have more than enough ipv4 address space for their needs.
Dislodging organically evolved protocols is always difficult and often
impossible.
