The new engine can work with collision detection removed, right ?
Would it be as fast as the old one in that case ?
Could that behavior be made the default, so that old users won't
notice any difference and new users won't be hit by performance 
issues until opting for a better placement ?

Of course it's still useful to improve the performance of collision
detection code but could be done with less pressure...
