I understand what Apple's intentions here are, but abstracting away a security risk is only inviting disaster, and it's kinda endemic of an issue throughout Apple's ecosystem: their whole game is about reducing the power of the end user. It makes sense from some angles, security being one, but it also impedes the freedom of choice. Instead of engineering their software to appeal to the lowest common denominator, they should be empowering people who want to push beyond that envelope and offering extensibility to those who want to take advantage of it.
