Problem with those is portability and convenience. Work breaks, waiting rooms, etc., I’m not going to have a controller with me so a slideout keyboard works better. Any situation I’d play mobile games with a controller would probably be a situation I could just bring a Switch or Steam Deck.
Get one of those gamepad cradles with USB-C (but don’t cheap out on it).
