I think that's the direction things are heading. If you look at the compositor API's they are trying to make the whole XAML layer easier to interop with DX because DX is where the perf and flexibility are.
Right, a big push to the XAML stack with the Anniversary Update was a lot of beefy pushes to what's called the "Visual Layer" [1]. A lot of the focus seems to be on making sure that you use high level XAML components and low level DirectX code side-by-side in the same windows.
There is a guy named Kenny Kerr that produced a library called "Modern Windows" or something like that. He has a PluralSight course...I think at least part of it is on youtube...where he demonstrate using it.
His stuff is just worth watching anyway. Awesome Windows dev and ISO C++ content.
