Now I re-added all the pkg: labels to get a full TAV test run.

Thanks for the detailed notes around the test changes. I think the overall benefit of this test is enough to move forward in merging. If anything a TODO could be added to the test linking back to this for a later investigation, but I don't see it being worthwhile enough to keep digging into the polling behavior.
