Sure, but the domain is untrusted even if validated. BTW, we don't 
validate c2s-connections.

XEP-0158 is already implemented on some servers. The result - users 
don't want to protect their rooms with captcha because there are too 
many clients which don't understand captcha forms and run on mobile 
device (where you cannot use a fallback HTTP method).
XEP-0159 and XEP-0161 are deferred.
