The issue if smashing locked doors. ToEE had no such ability - to smash or break object. And I did added that, as I personally do not like to play a Rogue in my usual 4 person party. In any case I thought the intention is justifiable, as RAW has it, so why not. But the problem is - everyone would just jump to using these options by usually chopping a door or a chest without any penalty involved. Even if chopping would break fragile objects like potions - one would just reload the save and try other means like for example the Break Object ability. Computer game is quite different to tabletop as allows reload, which essentially is metagaming. My domestic party just finished Expedition to Castle Ravenloft. They would never use any clairvoyance ability, except maybe Detect Evil, constantly annoying thing I tell ya. They would also chop or break any door they see, without any second thought. The only time they stop and were perplexed it was when their Paladin drop unconscious before final boss door (high level vampire). But even then they would go into, and then run out immediately. Afterwards they would regroup and use all uber potions available to them (like heroism potions, fly etc) . Essentially there is no simple bonus by not smashing or breaking a door. Except surprise off course, plus preparation of monsters.
