> It is possible Apple could design this differently in the future this is the way it is now and depending on their definition of pairing restrictions this could invalidate the security of a lot of phones in the field. Here's how they could do it: Require a device wipe for a security component replacement (touchid/faceid). On initial setup it does it's check/pairing of the newly installed component and works moving forward after which you restore your data from backup. If the component doesn't have Apple's signing key then that security feature has to be disabled. (home buttons without touchid are sold for old devices). They know how to do this, there's no technical reason why they can't. Sell the parts needed. Batteries? I think we need specific regulation here, there's plenty of companies that know how to build decent cellphone packs. Apple cannot arbitrarily decide to throttle performance if the pack delivers to spec and doesn't get outside thermal envelope. Pretty much every other component shouldn't have any restriction, if they want to send a serial validation you can generate a report on device for that's fine. Resellers would actually like this. But it shouldn't disable a loudspeaker if you bought a loudspeaker from a supplier other than Apple.
