Believe it or not, they thought of that when they created start/stop systems.

In cars with these systems, the back pressure in the engine's cylinders is greatly reduced via a variety of strategies including selective alteration of valve timing and purpose-built secondary valves. What this means in effect is that the torque required to re-start the engine is a fraction of a dead cold start, and even a fraction of a normal warm start. This should serve to minimize additional destructive wear on components.

In effect, well-designed start-stop systems do not create any additional wear on vital engine components versus the engine running for that same period of time.
