Out of the box it is not. As root I can't read or write files that the permissions say I can, among other problems. It is still possible to disable all this but they make it more and more difficult.

If I were to bet, I'd bet that the roadmap is to eventually make OSX be iOS, where you can't do anything except what apple specifically lets you do.
