I think this might be a strength of Diplomacy for current AI models - making contradictory plans with two different players is a perfectly normal human move, as is saying one thing and doing another, as is cooperating on round N and defecting on round N+1.

Agree that detecting it might be hard and that it might actually as is be beneficial, but that said, there huge difference in my opinion between knowingly breaking promises based on a heuristic and having no memory of past promises and simply basing current tactics on the present. Imagine if real world literally had no memory of the past or a single actor within it, it would lose out to opposing players as soon as they realized it had no memory, you could make any promise you wanted and it would literally forget it. Might be wrong though, just know it’s major issue with current chat bots and an easy tactic to tell if you’re chatting with a bot or not.
