I fully support your point. I also observed what you told here. Therefore we enhanced our Prefixlist-Generator doing counter-checks if an import statement also have a corresponding export - statement. Result is, that the prefixlist generation takes about 10 times longer, our caching database grew by factor eight (as we now also need to cache autnum objects of child- and grandchild-objects) ...  

So a "notify-on-policy" - how you called it - would be very appreciated!
