That does work if the name of the channel can be random (nameless). But I believe that there will be use cases where the name of the channel needs to be fixed. For PubSub/PEP this would be OMEMO, GeoLoc, etc., (although the situation here is not so bad, because the nodes don't get deleted usually). But yeah, § 6.5.3 could be sufficient in most cases. However, I still feel like having an optional atomic join-or-maybe-create operation would be nice to have. - Florian
