("But what does it add?" Other than a patina of realism, there's something dramatic and impressive about someone strong enough to tear apart a marble statue with his bare hands (Strength+unarmed damage>Hardness).
In 3e this was not modeled on the hardness rules, but on the Break DC. Same as 4e. Hardness in 3e had nothing to do with the Break DC. Someone smashing a statue apart by doing hit point damage is likely not going to be doing it in one blow.
It's cool to see the mighty blows of the barabarian's axe slowly shattering the Gem Of Ultimate Evil, while weaker attacks glance off it ineffectually.
Again, this is modeled in the Break DC in both editions. I'm starting to not understand your concerns. Break DC of objects exists in both editions and are pretty much identical mechanics.
In short, hardness-type mechanics help convey the character's power, because not EVERY attack -- even of the same damage type -- can harm a given object. In 4e, the Str 10 wizard and the Str 20 Dragonborn fighter both chip away at their target; the fighter a bit faster, maybe, but that feeling of inhuman power just isn't there, and that's a loss.)
The problem is, it really didn't. The only difference is usually 5-10 points of DR per hit. Even first level 3e characters could usually do enough damage to bypass hardness. There was never a feeling of "inhuman power" in hacking your way through a door or wall. It took X time, typically handwaved and you moved on.
I think the problem is, you are trying claim elements that belong to the Breaking Stuff rules with the Hacking Through Stuff in a While rules.
