Like if your worried about Governments tampering your device if you leave it out sight. I am sure they could easily get Apple SoCs on the gray market that do not have the boot ROM fuses set. So they could write what ever they want to that chip. Like sure they need to extract the key to decode your data. However, they could make it then appear that OS has a problem and needs to restored via iTunes. Sure it might reduce the sophistication needed, and maybe let smaller governments or companies do things. However, it still involves physical access to the device. If an attacker has physical access pretty much any system can be compromised in a lot ways. If anything this should be a boon to users. It allows them fully to use their devices they own. Honestly, it is inexcusable that apple makes users have to hack their own devices. You should have the option similar to enabling or disabling secure boot on your PC. As to the market for stolen iDevices. It still exists, but generally involves parting it out. Like sell the screen, cameras, and battery ect... Honestly, while unfortunate that things get lost or stolen. I don't see how this really changes anything.
