But isn't all that still necessary as long as the typical user isn't going to be opening their firewall on those ports to arbitrary incoming connections? That's the whole point here.

STUN yes (since you'll need to coordinate outbound traffic which creates the appropriate inbound rules), TURN no (since STUN will always succeed with stateful but non-translating firewalls).

And STUN scales almost infinitely better than TURN.
