Well, one of the items in the Evil Empress guide mentions that you should assume that other Evil Empresses and Overlords are smart enough to read and listen to these lists. But wouldn't that also carry the assumption that the heroes/heroines have read these lists too, making some of the suggestions obsolete. Particularly the ones dealing with renaming rooms for misdirection. Even if you were to use a different name for certain rooms, the hero/heroine would know that the original room names would be traps.
