IPv4 in the mid-90th was like a global pandemic that triggered a mass extinction event for almost all other network layers. AppleTalk, DecNET, CLNP, X.25/CONP, XNS, SNA, ... ("IPv4, the best pandemic ever" ;-) IPv6 was designed to kill & replace IPv4, and even tried to enforce it with sunsetv4 later on, aka: follow your "history repeats itself" model. That was well intentioned but in hindsight unrealistic. I think we learned that what happened with IPv4 will never repeat itself and can not be engineered by standards decree. Therefore, I don't think we could be successfull with periodic "kill & replace" IMHO we should have a strategy for evolution more like how e.g.: window 10 is managed, instead of repeating microsofts experience with the failing kill&replace through win7 and win8. Maybe first think about expansion through market segment profiles. I for once wouldn't bother changing the Internet profile (RFC8200) right now, but just think what the best incremental additional profile for e.g.: controlled inter-networks would be that could be added incrementally to networks where Internet profile is already running. This friendly co-existance is already standard practice for hundreds of millions of users anyhow for the parts of network technology where we do not need new standards.
