Someone suggested that engine braking could harm the AOS, but the greatest use of engine braking is from long descents in the mountains. Jake said living in higher elevations causes few AOS problems so I think this would imply that severe engine braking shouldn't harm the AOS.
Less atmospheric pressure in the mountains vs. sea level, less pressure differential on the diaphragm, less stress on the diaphragm.
