Huh, interesting to know.

If you're on level ground and actually take damage from a standing jump when landing, I would consider that a bit of an oversight and something the developers should look in to fixing.

As a mad man who literally runs and jumps around everywhere, I'd rather not accidentally die from simple exploration, or when scoping out land for a new base. (Though I am typically well-fed with H/H/S foods at all times.)

But I can totally understand fall damage; falling from a cliff should obviously have consequences. Based on the game Engine, though, it might be fairly difficult programming-wise to differentiate a user-initiated jump from a fall, or knockback from an enemy that pushes you off of something.

Regardless.. this is an interesting find.
