I don't think the problem is server-side. FWIW, our server has supported
STUN auth since day one. I expect adding STUN auth to other server
implementations would be easy.

The problem is practical. Our free STUN service is configured to not
require auth for STUN. And clients almost never do use auth for STUN.
It's the way STUN is being used that is problematic.
