Well, yes, but now that multiple providers are doing this the fact that
they are non-customer filters affects anyone who is not a customer of BOTH
providers, thus further encouraging people to aggregate.  I would not mind
seeing these filters become more prevalent, making it unreasonable for
people to become customers of everyone who filters to get around the
filters.  Renumbering is NOT that hard folks, and it DOES help.
