You and I are using different definitions of “commitment mechanism”, then.
The idea I am talking about is demonstrating to the other party that you are a nice, cooperative agent. For example by showing the other agent your source code. That concept has nothing to do with crime and punishment.
The type of commitment mechanism I am talking about is one that convincingly demonstrates that you are committed to a particular course of action under some specified circumstances. That includes commitment via threat of retribution—but also includes some other things.
AC’s stability is tangential to my point. If you want to complain that AC is unstable, perhaps consider TFT instead. That is exactly the same as AC on the first round.
