but I’m not currently aware of a situation where the 1.1 patch is needed that doesn’t involve some sort of multi-agent coordination
I think the 1.1 patch is needed to solve problems with coordination/amnesia/prediction, and moreover these are all the same set of problems.
Coordination: two people wake up in rooms painted different colors (red and blue). Each is asked to choose a button (A or B). If they choose different buttons, both get $100. One possible winning strategy is red->A, blue->B.
Amnesia: on two consecutive days, you wake up with amnesia in rooms painted different colors and need to choose a button. If you choose different buttons on different days, you get $100. Winning strategy is same as above.
Prediction: you wake up in a room painted either red or blue and are asked to choose a button. At the same time, a predictor predicts what you would do if the room color was different. If that would lead to you choosing a different button, you get $100. Winning strategy is same as above.
