No. Whole point of disabling long list of functionality mentioned in the article is so that — no - code is executed via that functionality on the device at all. You are suggesting something that go against whole point of turning it off. Browser already operates in “untrusted” mode. Apple’s iPhone systems and hardware are not designed to be separated. Even if the hardware was duplicated and completely isolated, the secure hardware would be in close physical proximity to non-secure hardware and as a result would be vulnerable to side-channels leaks and/or attacks.

You also are ignoring that a challenge-response counter-measures by the attacker would require direct and real-time action from the targeted users; CAPTCHA is a type of real-time challenge-response combined with private information would confirm that the target user is actively using the device being targeted.

If you think you understand something I don’t that’s fine, but I clearly neither understand what you’re trying to communicate, nor agree with what little I believe I do and have repeatedly attempted to explain why and you have repeatedly ignored my points. If I have ignore a material point made by you, please explicitly point it out.
