Hi ether, I think this should be implemented as a RegionFilter, that checks if a region contains a loop, and that can be asked for further information. In general I do not think this kind of analysis belongs to a region, but as you proposed some kind of filter could be applied. In the short term the passes who need this information could get it on their own....
