Avoid hard stops? What? Are you telling me that a car was manufactured that will have a decreased life if when driving away from the stealership someone pulls out in front of me and I need to hit the brakes HARD?
Who knows. Maybe the hard braking was thrown in to account for new brake pads/tires that need to be bedded or have their mold coating worn off.
I feel like minor machining variances and luck of the draw (or pull from parts cart) when your engine was built, and ongoing vehicle maintenance will matter most on what happens down the line. But really just dumb luck within the range of how well a specific engine was designed and/or built.
