I thought TURN was for symmetrical PAT, not for proper NAT (which just needs STUN for address determination) or full/restricted cone PATs (which need STUN for address and port determination, and then, in case of restricted cone, performs a hole punch).

Standard-conforming IPv6 at most allows prefix translation (i.e., proper NAT, not PAT), which wouldn’t need it.
