I don't imagine that realism is the goal here. If you want realism, you'd have to handle sharp melee, blunt melee, bows, and firearms differently, and obviously there's no realistic answer to worn-out sci-fi weapons. I'd assume it's to make weapon management more accessible, so you don't need to check the individual stats on weapons when deciding what to equip, possibly with a spreadsheet open on the side. That's fine with me, but I'm a more casual player than some. I can definitely understand the desire for a more detailed system, which would also be fine with me.
If I were doing it with realism as the goal, I'd probably set sharp to do more damage but lose penetration, leave blunt unchanged, have bows lose accuracy and damage, and make firearms have a chance to not fire equal to the damage%. Sci-fi weapons I'd make explode at the damage% rate, mostly because I'm a jerk.
