Probably tremendously late, but imagine the following.
Suppose that there were some objective that you want to happen for your alliance, and you don't want it to happen for your opponents. However, neither of you want it to happen to nobody.
As an example, imagine there was a goal from Zone Zeal at midfield. In autonomous, robots would attempt to displace this goal from the middle of the field, bringing it back to their side of the field. If an alliance succeeds, a randomly-selected robot on the other alliance is disabled for ten seconds. If neither alliance does it, a randomly-selected robot on both sides is disabled for ten seconds. Nobody wants to have their power robot disabled, right?
(If this actually makes it into the game, I apologize.
