I think bandwidth weight isn't appropriate for this. If we think the cost of
running a HSDir(+IP) is too low, we should increase that directly. This is a
good case where we can benefit from the many honest-but-not-well-funded
relays. Concentrating even more traffic and information onto the
highest-bandwidth relays isn’t an improvement.
