The IPv6 spec looks long because it also includes protocols that are separate on IPv4 (DHCP/SLAAC, NDP, depending on the document ICMPv6, mirroring DHCP, ARP, ICMP, NetBIOS, etc.), as well as the addressing schemes that were different RFCs in IPv4 such as multicast/unicast/network classes/subnets.
As for the implementation: just about anything more powerful than an ESP32 has the entire protocol implemented and running already.
As long as the SDKs to apps make it simple, we'll be good. I haven't seen much, so far.
What do you mean? Apps for iOS and macOS have had perfect v6 support for a long time because of this. Linux has unified address families for netfilter and internet sockets that abstract the details. Various programming languages have perfectly fleshed out standard library data structures and functions, etc etc.
