They easily could, agreed. They even might? It's not unheard of for Apple to release software on other platforms, however uncommon it might be. It's certainly not the kind of thing they do right at the time of release. I don't imagine you'd get much penetration relative to running it on every device at the OS level, though. Probably rough on the battery running in userspace? It doesn't seem like it solves a problem most people are likely to have.
