The reason nobody is adoping ipv7 is that all the so-called advantages of ipv6 are all disadvantages, except bigger address space. If there were some advantage then we would be willing to invest the substantial time and money to switching over.
* get rid of NAT - I like NAT, it helps me keep the private parts of my network - well - private
* auto-configure - what an awful idea, a recipe for disaster
* every device their own ip - um why?
And then there's the cost of implementing. Just as a simple example you can currently ssh or rdp to servers without needing dns to be working because you remember those critical ips and can type them in quickly. Try doing that in the ipv6 world. So you need new infrastructure to manage your addresses - that's not theoretically a difficult thing to do, but just one more reason to put off a non-urgent (to the people with ip4 addresses) change which gives no upgrade advantage.
There may be advantages to ISPs and network managers, I don't know, but they obviously aren't big enough that ISPs are pushing this change to consumers.
