Even with IPv6 you still might have stateful firewalls allowing only for outbound connection at both ends (e.g. a CPE a.k.a. “WiFi router”) and to establish communication you’d need to punch a hole in those firewalls.
That’s true we won’t get rid of hole-punching with IPv6. But at least it will get rid of TURN.
The hole punching is so much simpler because you don't need to guess your own address and port - you just know it
