I hear you. I literally cant use any commercial tracker because of a alternating strabismus and the midas touch effect is a nightmare. I'd argue Apple did that because its such a mess on regular OS where the primary input method isnt eye gaze. (They did that with iOS too - match the OS and UI to the primary access method)

I'm not sure I can believe this "This system is likely already working better than an eye tracker would for cursor control" - the training to use this stuff isnt just 'magic'. I do agree though with "and it will certainly improve" - yeah iterate.. iterate..
