I think it could be because it doesn't provide the value to the development teams. Why chase a memory leak or a CPU bug if it's just being caused by your fault testing app? To prevent the negative effect of random machines dissapearing though.. that's a challenge that involves good ops, devs, even UI/UX I would imagine, and closer to something that users experience negatives because of in real life.
