I tend to agree with this. RFC 6120, section 7.1. says that clients must do resource binding, section 7.2. declares support for it mandatory in the client, and in section 7.4. it is definitely stated that (hilight by me) > [...] the server MUST include a <bind/> > element qualified by the 'urn:ietf:params:xml:ns:xmpp-bind' namespace > in the stream features it presents to the client. > [...] > Upon being informed that resource binding is mandatory-to-negotiate, > the client MUST bind a resource to the stream >>>>as described in the > following sections<<<<. This, in my opinion, means that RFC 6120 has to be officially amended to support Bind2 as in case of conflicts between a XEP and the RFC, the RFC must take precedence. Apart from the formal argument, disregarding RFC 6120 and revising core XMPP functionality via a XEP means that a good part of RFC 6120 (namely section 7) does not reflect the reality anymore when Bind2 is accepted. Someone creating a new XMPP client naturally starts by implementing RFC 6120, only to discover that it is obsoleted by practice. I do think that such severe revisions deserve a note in the RFC.
