I am a huge fan of path filtering, but I have so very little paths to
maintain that I can say so. I guess most operators to not filter paths,
and building prefix lists is more or less current practice. Just from
what I have seen so far.

I asked about best practice about building filteers from IRR data a
while ago on NANOG, but there were not really an answer.
