Everything is in the starter enclosure no need to access the motor, much smarter system....Rod
The system you describe works well - the human replaces the centrifugal switch. But centrifugal switches don't give a lot of trouble, especially in TEFC motors. The advantage of using a centrifugal switch is that the motor is brought up to speed "automatically" without any additional action other than applying power.
I'd rather just have to turn power on when I want to use my table saw, without having to hold the button. But I suppose you get used to doing whatever you have to, and it becomes second nature.
