Note that I didn't say bogon filters were a bad idea.  I said that the
concept of installing a bogon filter and not adjusting it to fit the
changing realities over the years was usually(*) a bad idea.

(*) usually - if your business model allows you to reliably enumerate
the list of sites that you want to talk to, feel free to declare everything
outside the 3 /16s you actually need to talk to a "bogon".  Note that in
the preceding sentence, "reliably" is another important word... :)
