That would fix the Touch Bar problem, but not the keyboard. And you can't buy a 15" without the touch bar. And you can't get the most powerful chips without the touch bar.
So no, that doesn't solve the problem. I understand there is some number (I personally believe miniscule) who like the touch bar, and I am not arguing that Apple should get rid of it entirely, just that they allow you to buy their most powerful machines without having to get one.
I actually like the Touch Bar, with one exception, the stinking escape button on it. I'm a developer and server admin, so I do a lot in the terminal, and not having a real escape button is annoying as heck. Other than that, it's pretty handy, especially with Better Touch Tool installed where you can create your own buttons that are app specific.
