I was going to push back and say that those are things that Apple's own products also don't make use of (other than the iPhone itself), so excluding those from third party use isn't giving Apple an advantage in selling additional products, which is what I think the whole complaint is about. If Apple is using restricted APIs to sell additional stuff that works with iPhone, but competitors can't, I can see why that would be an issue the courts would be concerned about.
So the "I was going to" was before I realized that Apple does have just such a product: The Apple Watch. I haven't used one, but I expect it wants to work as an extension of the phone, so it would need to do many things that normally are only allowed to be done by the phone itself, including access to all notifications and sharing WiFi login data so it can also connect.
So, yeah, that's an issue.
