I also don't think the maintenance burden is minor. We really only get away with that stance because we continue refusing to allow block-based fsed to be mounted in users namespaces. It's so trivial to find on-disk image bugs for non-actively maintained fses that I don't see the point in keeping them around unless there's an actual future for them.
