It would hard to "adapt" levels to this. For instance, while a bot could completely rock at Battle2, sending it to a Foo Races level would be a disaster. The only way around this that would not require a really really really complexly executed solution would be to tell it specific things about the level like "Go up, not to the right if you get a copter item on battle1." Of course, the programmers couldn't do this for every level that is hosted often. Thus, the bot would have a huge disadvantage, which is one of the various reasons playing bots were scrapped (no pun intended) after these issues came to light.
