Thing is, as soon as that toggle exists, it can be exploited. That affect all users, including ones who have no intention of enabling it.
It wouldn't be a toggle.
It would be part of the terms/conditions you agree to when setting up a new phone or downloading a new OS update. Or more likely a one-time required acknowledgement next time your phone is opened.
With the language essentially saying, if you choose to sideload, you're on your own if your phone is compromised or you suffer from being hacked or damaged in some manner (privacy.security, losing money, etc). Along with an "I agree" button.
Apple will figure out the best way to handle it.
