Should #Conversations_im add stun.conversations.im as a fallback for #XMPP servers missing XEP-0215: External Service Discovery?

I’ve hesitated to add anything resembling "calling home" (no update checker, no metrics).

However, the main goal here wouldn’t be improving A/V call success (though it helps) but making P2P file transfers more reliable. Many servers still lack HTTP Upload, and the refactored Jingle File Transfer would benefit greatly from a fallback STUN server.
