Even more so: why is disabling superior to dropping??? It is at most an extremely minor convenience to be able to re-enable it without having to re-create it, in that you can, presumably, just re-enable by name without specifying the constraint details. In other words, in my opinion, it is a virtually worthless feature. (Typical "enterprise software" feature creep.)
