When they decide to do it, you will be astounded by how much they can draw out in that super between inspections.. Even if you inspect once a week..
No, it is not really a problem to scrape it out and clean up the mess if and when they do decide to make use of that space, but having them build all that new comb in frames is much preferred..
I have no arguments about doing it that way at all, but did learn the hard way to use the 4 jar stands over the inner cover hole, or put one jar in the hole in the inner cover.
