Thickness is only one factor, and it is easily measured. Surface condition and heat effects are other reasons to change rotors.
I change mine because it is cheap to do so, improves braking performance (surface condition, and greater thermal mass), and reduces the likelihood of having to go back in for a noise complaint. I got 90,000 km out of rear pads on our current vehicle, fronts are still good. Not a tough decision.
