Heh, fortunately that isn't much of a concern. These are all things that a good programmer would find within 30 mins when they sit down with a profiler to eek out a few more fps or free memory. The intention is not to hide these from other engineers, but to keep a bit of performance in the bag for when needed at the end of the project. When you absolutely must hit 60fps, or fit everything into 32mb of RAM, it can be invaluable.
