Valve has experience already with making m+kb games playable via a trackpad on the Steam Controller, so I'm confident that the trackpads on the Deck will be good enough for a decent chunk of games (though I'm not about to try Dota 2 on the thing).
Not every game will be a perfect fit, certainly, but I've had a great time with my Steam Controller playing things like XCOM, Prey (2017), and Divinity Original Sin. IIRC Civilization 5 was explicitly a part of the advertising for the controller in the first place, as a way to play mouse-heavy games from the couch.
