Hardware lights are so fast for that very reason ... they don't check visibility and they don't cast shadows.
This might be useful, but I think you'd get enough artifacts that it wouldn't be all that useful. Like, an entity is partially behind a wall but it still gets entirely lit because the wall isn't throwing a shadow.
