Well, sure. But I think it's telling that the only mentioned example of a Mac app that would benefit from this "iOSization" is one that so clearly breaks the iOS walled garden model.
That kind of utility usually works by simply muting the volume on shutdown. It's not a nasty hack, and I think it's presumptuous to assume that it would be excluded from the App Store.
"Apps must be self-contained, single application installation bundles, and cannot install code or resources in shared locations."
I don't see how the utility in question could be a single app bundle (no daemon, no startup script, etc.) and still perform its job of muting the volume on startup.
