The answer is an emphatic NO. The uterus is still designed to contain and protect an embryo/fetus regardless of whether the uterus works or not, or whether other failing body functions will soon render it useless. You don't say a person's heart isn't designed to pump blood because the heart didn't develop properly, or that it wasn't designed for that purpose because their lungs are failing. The same goes for any other organ/muscle/limb regardless of whether or not a person would have survived long enough to use it without medical aid.
