Ok, so it seems the reasoning here is that XEP-0397 is the solution because when you're using it you're not trying to log in anonymously with a pre-specified JID (which is not allowed) in order to resume a XEP-0198 session, instead you resume the session by means of a token (which implies a particular JID). The difference is very subtle, but makes sense to me. Well, to come back to Georg's point of not deprecating BOSH until we have a solution, it seems that XEP-0397 would need to be included in the compliance suite, at least for this particular use-case (maintaining anonymous logins over websocket).
