They can still prevent the JIT from working because the resulting native code would not be signed. That would result in worse JavaScript performance in such browsers, but considering today’s hardware and software optimizations, it may not matter that much in practice.
Yes, but the point of the law is that apps that you install that are not from the official store actually have to work. It even has clauses so that installing stuff from different sources than Apple can’t intentionally be a worse experience than the official app IIRC. That might be just for messaging though.
If you can sideload an app there’s nothing Apple can do to stop you from shipping a new rendering engine.

I don’t think they allow JIT in their App Store apps either.
