And that right there is the direction Apple is going, that is turning off lots of people. Giving customers options is quickly disappearing from Apple's product lineup. The movement of iMac to not allow upgrades, due to the desire to make the iMac thinner of all things, along with the glued in RAM and proprietary SSDs in the rMBPs is also greatly limiting customer choice.
The lament of the fanboi is that you simply do it Apple's way, or hit the highway. Customers are better served by choice. Why? Because you can chose to go with the default/what is pushed by Apple. If you are not given any choices, then your only choice is to look for alternatives to Apple. You see that with screen size in the iPhone, you see it with inability to customize iOS, no multiple user logins. And that is just the iPhone/iOS. Move it to the Mac side, and you have many other examples.
Again, the fanboi response will be - ZOMG APPLE IN THE 90s!!!! Lots of choices = death to Apple!!!! Given an unintelligent approach, you are correct. Allowing an intelligent approach(allow minimal customization for iOS layout), would work, since you can simply IGNORE it.
