Simple: Overheating any engine entails risk of component failures, particularly an aluminum alloy engine, it is very risky business. We have had to replace multiple engines that suffered from that. Overheating can thermal expansion that can cause components to warp or lose structural integrity. Cylinder head cracking, and cylinder liner problems can result.
When we get one in that has been overheated, we typically run some extra diagnostics (pressure test the cooling system looking for signs of internal cracking, and run a leak down test on the cylinders) before returning the car to the customer, just to prevent any "come backs" from problems introduced by the thermal excursion.
