A lot of focus about the problems with ref advertisement is about the obvious problem mentioned above (a bad problem indeed). I would like to add that there is another related problem that all potential solutions to the above problem do not neccessarily improve. When polling regularly there is also no current efficient way to check on the current state of all refs. It would be nice to also be able to get an incremental update on large refs spaces.
