And, as everyone knows, nothing ever goes wrong. There is never
anything on the runway that shouldn't be there. You never have to
land on a shorter runway than you intend, and you never land at higher
than expected density altitude.

Not to mention off-runway landings... there's the real rub for safety.

If the runway is smooth but short, you may have the choice of what to run
into at a reduced speed. If it's an off-runway situation, you'll be
touching down at whatever flying speed, and encountering surface
irregularities at higher speeds.

It's easy for folks to only consider some emergencies when justifying their
risk profiles. Of course, I've never done that :-)
