They've done this before with other internal hardware, and they'll do it again if it means keeping up with supply and demand. IE; it's not unheard of to have two different manufacturing companies work on a device in order to keep up with demand. The only difference is that this time someone noticed, and some decided to make an unnecessary stink over it.
Like I said, there were reports that prove the differences between the two chips. I imagine Apple will stay away from going down the same road on a part with tested and proven differences. It doesn't matter how small those differences are to you. They were there. And that point can't be disputed.
