I would argue that it's a political and economic problem that certain devices exist without the capability to support the latest HTML5/CSS3/JS standards. I worry that your idealism will serve to only upset users, who will undoubtedly blame you, not their ISPs. It would be wonderful if every device conformed to the RFC, but much like certain browsers don't behave to spec, certain implementations of many other internet technologies suffer the same problem. Of course, I am a proponent of IPv6 deployment (I doubt you'll find many people who are not), but I can't agree with your assertion that IPv4 has no place on the internet, it's practically impossible to force a transition merely by ignoring the world around you and trudging on.
