just tried it for testing purposes (this thread is not about the usefulness of the components), went to the change panel, removed virtualization and rebooted. SafeZone is still there. There's nothing to remove the safezone independently so... There doesn't seem to be a way to remove it from AIS. Nothing to remove the auto-sandbox either by the way. Any comment?
edit: I might be wrong but I thought I saw the SafeZone in custom install options during the beta...
