Xbox app becoming the DeFacto platform

Hi. I'm no tech expert but I do wonder if the Xbox app could be a native download on Xbox allowing us to play windows games and partake of PC Game Pass. I also do think that the Xbox console experience could be migrated or integrated into the Xbox app making it the platform that is truly compatible and this way rather than porting games to other platforms the app could just be on those platforms. As long as the app functions natively it would be adaptable to any device or console.
