It sounds to me like its a tool which is available to be used when needed and when no better workarounds exist, and it is slowly but surely being adopted as needed.
For a long time, there really was next to no progress. Between the introduction in 1996 and about 2011, there was very little adoption. And since 2012 when pushing really started, we're at about 50% globally, with large variance by country and network type. 15 years between creation and real deployment seems like a lot, and 15 years of deployment getting to 50% also seems likes a lot.
But wikipedia says touch tone dialing was first offered to consumers in the 1960s and didn't become majority until the 1980s, so maybe 30 years isn't that slow.
Things have developed so much, a Internet2 is still going on I take it, however is more focussed on university research.
As ever a killer strength is something that draws people to a new technology, I imagine there's various demographics that benefit from use of ipv6.
Further I imagine that there are some levels of criticality which when reached are more self sustaining (dare I say it the network effect?).
I've been posting this graph over the years, and it really has slowed down hugely close to this 50%. This is a global ipv6 support, so some countries are racing ahead, others weirdly like Denmark have a stash of ipv4 addresses and seems content.
France and Germany are at about 80%, but there's the rest of the world of course.
That seems to be a promising approach.
They use 464XLAT, basically NAT64/DNS64 with some extra cooperation on the OS’s part for backwards compatibility with apps that hard-code IPv4. You get only a v6 address, and your OS basically synthesizes an v4 network on your device in cooperation with their NAT64 router. But all the bytes going from your device through to their towers are ipv6. Talking to a v4-only website uses carrier-grade NAT64 when leaving the t-mobile network.
To the local network, it looks like there's native IPv4, but it's translated to IPv6 by the gateway, and sent to the "nearest" NAT64 PoP to be translated back and sent along its merry way.

Personally I think the design of IPv6 offers very little benefit; supposedly the Dept of Defense/Dept of War holds some 175 million IPv4 addresses, with other companies also holding large allocations - that should have been addressed 25-30 years ago as an administrative matter.
The $1 to $5 a month to have excellent, reliable connectivity (that no residential connection provides), DDoS protection, and isn't tied to my home IP outweighs any home hosting benefit in my experience.
...but that's based on pre-IANA-runout rates, though, and doesn't account for the pent-up backpressure of demand. So probably a lot less, in reality.
Not even remotely worth the effort, even if there were a legal pretext for "reclaiming" IPv4 space (there isn't; there's already precedent denying it).
