As mentioned by Jérôme, Tracker already needs way more than those.

I think the best solution would be to introduce a flag that tells a
live query that you want to monitor all query results automatically.
That's the only way of preventing the race condition between sending
and receiving the query changes.
The code that I removed in BFS solved the problem as well (always
sending query out/in events in this case), but was not without problems
either (it would not know the original directory, so was not able to
send a correct B_ENTRY_REMOVED messages).
