Unless some mad max shit happens im never driving a car that many miles so IDK why we are talking about the effects of a feature on the condition of the engine far outside the period of original ownership.
The link below says most vehicles are in the junk yard before they reach 186k miles.

It would take me 26 years of only driving 1 car to reach that mileage. If you drive significantly more miles you probably don't engage the start/stop very often because you are on the highway all the time.
