Maybe this makes more sense if we view this as involving three parties: Apple, users, and app developers.

On OSX at least, some apps are developed by third parties whose code isn't easily scrutinized by Apple or by end users.

I think Apple's policy helps users navigate that situation pretty well. But I also can't see any good reason to prevent users from disabling that feature in a fine-grained way. E.g. per app and/or temporarily.
