AbigailII: I don't know exactly what was the promisses done, so it is difficult to speak. But you are probably right that the implicit meaning of "autopass will be implemented" should have been "you will be able to use it in all your games".
Excellent point about autoplay, I didn't think about it ! And actually, in some games like Ambiguous Chess, this feature is a real playing help. Sometimes I click on a square thinking that only one piece can go there, and then the system doesn't move it there, making me see that another piece could move there too (and that it would be very costly). We indeed have half an autopass and half an autoplay.
