Not to the client, no, but it's important to the implementation of the
proposed server components (gateways and nodes) which have behaviour that
is beyond that in the XMPP RFCs and requires standardisation for gateways
and nodes from multiple vendors to interoperate, as went my justification
on the other thread.

If the XSF were not to host this specification, where would the appropriate
place be? Rayo is already an XEP, and this is the specification of specific
behaviour of XMPP components, so I don't really see how there is a more
suitable venue...

Is that not something that can be dealt with in the post-publishing review
