Will there ever be Mouse and Keyboard support for Game Pass on Android?

I use a Tablet, I know the app works great with a controller, but there are just some games that work so much better with mouse and keyboard. The main two genres being FPSs and RTSs, RTSs being almost unplayable with a controller, at least in my opinnion The ability to have choice would be great. I've been thinking of switching to Shadow, since it has support for pretty much any controller/keyboard a normal PC supports. So is there at least talk of adding this to the Android app, or should we not expect this?
