  >backdoors inevitably leak? Well, now you have a trivial jailbreak vector

the discover-ability of an exploit vector relates little to its trivialness, definitely when considering the context (nation-state-APTs)

You can hold the enter key down for 40 seconds to login into any certain Linux Server distro, for years. No one knew, ez to do.

You can have a chip inside your chip that only accepts encrypted and signed microcode and has control over the superior chip. Everyone knows - nothing you can do.

Nation state actors however, can facilitate either; APT's can forge fake digital forensics that imply another motive/state/false flag.
