Actually there is already a standard for address discovery - STUN. By 
the way, you didn't tell why this XEP is useful and why it is better 
than STUN, or when to use this XEP and when to use STUN.

This XEP adds incomprehension: a Jabber developer might be confused 
which approach to choose: this XEP or STUN.

Agreed. But I think we need to use a common well-tested solution, and 
not invent our own without necessity, if possible.

BTW, STUN has a protection from poorly written ALGs which rewrite IP 
addresses, that's why MAPPED-ADDRESS is now deprecated in favor of 
XOR-MAPPED-ADDRESS. This XEP doesn't have such protection.
