I wouldn't characterize the ISS as being over cautious at all. One of the main benefits of running on a simulator is that it can easily catch this sort of error in you code. It can be very hard to find these sort of errors when running on real hardware: the uninitialized value might not cause a problem most of the time (but it surely will during product demos!).

If your code is reading values off the stack that it hasn't set, it could potentially signal a problem (unless, as in this trivial case, you don't actually use the data).
