I disagree. This is an annoying compromise for something that doesn't need compromising. My phone's home screen is cluttered enough as it is and now I'll need separate apps for all the games in my Xbox library and those on Game Pass? I'll also need to download a redundant amount of code for each game and may not be able to play certain games due to Apple's arbitrary rulings? I'll have to dig through hundreds of games on Microsoft's developer page just to peruse through Microsoft's non-gaming apps to stumble upon something like Family Safety or Math Solver?
This sounds like a huge pain in the butt for users and kind of loses some of the value proposition of game streaming: trying games instantly, not needing to download anything, and not taking up a bunch of space for your whole library.
