Comment (by arma):

 To be clear, the proposed idea is that when the directory authorities are
 creating the consensus, they should, as part of the algorithm to turn the
 votes into a consensus, make sure that no relay has more than x% of the
 consensus weight.

 We earlier imagined having torflow (or later sbws) make sure that it would
 never give too high a weight to any single relay. But if each bwauth
 chooses its numbers independently, and then the dir auths just take the
 medium of each, that won't actually ensure that no relay will have more
 than x% of consensus weight. The only place to reliably guarantee it is in
 the consensus formation process.
