Comment (by eschnett):
I now think that generating empty bboxes is fine. They are generated if the domain contains "spurious" buffer zones, i.e. buffer zones that are not needed. For example, if you have 9 buffer zones and create a 5^3 refined region far away from anything else, then this 5^3 region does not contribute anything -- it has no interior, it consists only of buffer zones that will be set from the next coarser grid, nothing from there will be restricted back to the coarse grid.
I am also working on a patch...
