Understand very little about the problem space and complain about the best-compromise solution that the people who do know what they're talking about came up with. It's a very comfortable position to be in, I recommend it to everyone.
Things look fine to me, the reality is dual stack, a full ipv6 transition is idyllic and pointless.
I'm certainly not the first ipv6 critic, and you may notice the nuance that I didn't advocate for not using it, I just don't advocate dropping ipv4. Furthermore it doesn't matter if I advocate it or not, like a train ipv4 keeps going, it's only ipv6 that is advocated.
IPv10. The next IP version number that is unassigned, that is conveniently 4+6.
Basically something that is not breaking compatibility with IPv4 and doesn’t require those dual network stacks nonsense.
Then it's not IPv4 and is not compatible with IPv4.

What's the current rate of v4 address space consumption? How long will this block last?

This is, by definition, not backward compatible.
