Okay the Gizmodo headline of "having to be approved by robots" might be a bit b-movie ish, but this is down to the volume and security game. Steve's already talked about the issue of volume in an App Store, but no matter what solution comes out of arguments like that, there's still a certain level that applications should be reaching in terms of code - don't crash; don't brick the machine; don't do anything that costs the user something without asking them; and so on.
To be honest the howls of protest can just stay as that - howls. If you use undocmented features and put a phone at risk, then that's fine... if it's just your phone. You should be allowed to do that. But to release that into the wild? I'm not so sure.
