I don't know if that's a realistic use case. In such a use case, I would envision the browser putting a watch on "/". A watch sees all events in the subtree rooted at that point and you must apply a filter that filters them out if you're not interested (filter on WATCH_INFO_IN_SUBTREE using info_filter and info_mask).
