You're forgetting removing the scrapping penalty. That was the big difference between the chunks and scrap iron. The penalty lead to decisions like, "Do I keep this Iron Axe to melt down or scrap it here and lose a big chunk of the burn." All the while you hear a zombie getting closer and closer.
It made the player slightly uncomfortable which added a sense of conflict. It added decision making in looting/mining, especially on MP servers where you couldn't just chuck what you couldn't carry into a chest in the middle of the road. Now it's just another dumb watered down system. But, I guess anything that takes a precious second away from shooting and looting is "clunky" anymore.
(Also, that wasn't sarcasm, it was hyperbole. Good try though big guy.
