I believe the force-reset button combination is a firmware (read-only) routine for that reason. See: https://support.apple.com/guide/iphone/force-restart-iphon

  Firmware updates are a thing for other devices. Sure, the force-restart logic should be stored on some separate device that isn't touched by any part of OS other than the firmware updater — but are you sure if it really is or should be read-only?

    Nope I am not sure. Not going to lie: I do place a significant level of trust in Apple's statements regarding their security architecture / model.

      I'm inclined to place some trust in Apple too. Is there any statement that force-reboot is a security feature?
