I'd be fine if breaking containers gave less loot, or dropped the durability of any equipment inside, etc. It is a polishing feature, though, which (if implemented) needs to happen after all the loot tables are balanced, and given limited resources as the release approaches, may not be high on the to do list, even if Larian would like to do something like that.
I'm not sure. Do not forget Larian stated that Divine Divinity scored +10% for the english edition than the german one when it was released, and that only because the english one had a better loot algorithm. Of course, back then this included looting from npcs as well, and not only for the smashing/forcing style.
