 Replying to [comment:28 dgoulet]:
 > But also, you seem to be suggesting that it would be useful for relay
 operator to maybe control that value somehow which means it needs to
 become also a possible torrc option? (the patch doesn't have that).

 Ah, no, I think the way we'd let relays defend themselves is just by
 turning the knob down on the network-wide consensus value, so relays
 automatically defend themselves more aggressively.
