I guess the problem is that Apple don't need to do it; lots of people would like them to do it, and maybe they should do it, but it's not hurting their bottom line much so they can just continue as they are. Unless a whole heap of customers suddenly decide to buy different laptops instead over it, but I'd not be betting on that.
Arguably, this might happen in the long run. They might slowly lose dev over the years if they neglect documentation, which will eventually hurt the app ecosystem. Eventually, that'd affect user.
Very hard to say if the problem is serious enough yet though.
