It would be helpful if there was a report that could show all extents (including component level extents) used by repositories. In my situation, I'm managing 16 repositories using ~2,200 different extents. This kind of report would make metadata cleanup much easier. Otherwise, I have to manually look at the controlled values used by each repository, and they don't always load because the list is so extensive.
At the December 8, 2020 meeting of Dev/Pri, we decided that while the specified report could certainly be useful under certain circumstances, it does not seem like this would be used widely enough to warrant inclusion in the core code. Custom reports will be available in a future release, but there is no timeline for this.
If other institutions desire this report, please comment and we can reconsider.
