This is the single most aggravating thing in the entire game for me. (besides maybe a rogue troll smashing my base)

There is no debate here.  ok I guess there is. it allows for cheesing the Ai when you're below them on slopes.
still, the benefits outweigh the drawbacks, and I'm not about to give up a qol improvement in favor of cheese tactics.
Just to list some more benefits:
Being able to properly aim at trees/rock you're chopping. No more mindlessly swinging your axe at a log or stump that is just below waist level.
More engaging melee combat. Leaping over an enemy as you cleave their skull with your axe.
The only reason I can think of that it wasn't done was because it can lead to strange things like the lox attacking you through it's own back.
But I really don't care. the benefits far outweigh that single drawback. It's barely a problem anyways.
