Of course there are multiple ways to take customer routes, one of which is
filtering. A unique situation such as the CW/PSI mess would have called
for a prefix filter tweak, which, albeit, not automatic, relatively
painless on a small scale (i.e, you don't have to change hundreds of
customer routers because they don't have the talent themselves).
