Exactly. The whole point of a tablet is to show the buttons you need when you need them (and only then), without an external device taking up space whether you need it or not.
What if I want the buttons available without taking up space on the screen whether I need it or not? The information density of a screen collapses in on itself when it is completely crowded out by control surfaces, so your very argument can be used as a counter-argument.
There are of course exceptions to every rule. A specialized controller might be suitable for a few applications. When talking on the scale of Microsoft and general-purpose tablets, the market for such specialized controllers are vanishingly small; great for a niche, but a paltry offering from a company in desperate need of mass appeal.
