[Standards] Re: UPDATED: XEP-0402 (PEP Native Bookmarks)

TL;DR: autojoin only means whether to join automatically on login, it's not for tracking/controlling which MUCs you're currently in; "I don't want to join automatically" is not equivalent to "I want to leave now."

I completely agree that the decision of what to do wrt join/leave should be up to the client and not part of the XEP at all. However the XEP already had language like "On the other hand, if the event is a retract notification, the client SHOULD leave the room immediately." and so this led to specifying an inconsistent UX (as opposed to not specifying UX at all, which would be preferred). I think the solution in practise will be to ignore the SHOULD in clients that know what they are doing.
