I agree that TE deaggregates will be first to be filtered, but I think 
it's important that any policy we put in place doesn't create a whole 
bunch more small unique routes covering end-sites.  That will both 
reduce the need for filtering, and make sure that there can actually be 
covering aggregates that can make it safe to filter distant deaggregates.
