LC5 - Need richer control over which queues/exchanges are propagated, and
which are not.
-Question: is it possible to miss an event on subscribing for
-configuration propagation? are the initial snapshot and subsequent
-events correctly synchronised?
+LC6 - The events and query responses are not fully synchronized.

+ In particular it *is* possible to not receive a delete event but
+ for the deleted object to still show up in the query response
+ (meaning the deletion is 'lost' to the update).
+
+ It is also possible for an create event to be received as well
+ as the created object being in the query response. Likewise it
+ is possible to receive a delete event and a query response in
+ which the object no longer appears. In these cases the event is
+ essentially redundant.
+
+ It is not possible to miss a create event and yet not to have
+ the object in question in the query response however.
