It became a problem precisely the moment AWS starting charging for ipv4 addresses.

"IPv4 will cost our company X dollars in 2026, supporting IPv6 by 2026 will cost Y dollars, a Z% saving"

There's now a tangible motivator for various corporate systems to at least support ipv6 everywhere - which was the real ipv6 impediment.

Residential ISP appear to be very capable of moving to v6, there are lots of examples of that happening in their backends, and they've demonstrated already that they're plenty capable of giving end users boxes the just so happen to do ipv6.

Yes and setting up a single IPv4 VPS as load balancer with SNI routing in front of IPv6-only instances solves that.

Most people are probably using ELB anyway
