-----------------------------+--------------------------------
 We don't currently weight requests to authorities.

 While the fallback directory code uses the weights, we could assign each
 fallback the same weight, or leave the weights out, and have them assigned
 the default weight.

 If we didn't weight fallback directories, this would potentially improve:
 * the statistics calculations on authorities,
 * the privacy implications of high-weighted fallbacks seeing too many
 client requests.

 (Implementing this ticket would obsolete #17888.)
