That's actually an interesting point - TAS tools should make it possible to make any game into an AI training environment. The one thing I would say about that is that speedrunning is a really, really difficult thing to do with a gradient descent approach; you can get really optimized with a particular strat, but getting substantially faster often requires drastically different strategies - which can only be discovered with a very broad knowledge of the game's systems, in areas which you will likely never see if your only experience with the game is speedrunning one particular strat exclusively. And exploration of the game's space during a speedrun would kill your time.
