Three things spring to mind:
1. IPv4 will persist, possibly forever. There's really no compelling reason to migrate to IPv6 other than address space and we've had decades at this point of getting around this problem with various flavours of NAT.
2. Ossification. We've taken the quite reasonable step of discarding any packets or traffic we don't understand from a POV of minimizing threats. For example, there were cases of bypassing security using packet fragmentation. But this makes it increasingly difficult to extend the protocols (eg reliable connectionless messaging aka a reliable UDP).
3. We don't really have a good solution for roaming. If you switch hotspot and get a new external IP it'll typically break your connections. A lot of work has been done to workaround this (eg carrier-grade NAT for mobile IPs) but identifying an endpoint with (address,port) (or just (address) for IPv6) is less than ideal.
