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.
