Name them and tell me if it wouldnt be smoother just doing that shit with whats already available on the controller.
Ghost of Tsushima = Swiping different directions did different actions allowing other buttons on controller to do other things.
Multiple games have used the touch pad as 4 mappable buttons. Elite Dangerous is one of them and I think Project Cars, but there's more.
Many games use it as a split button allowing an additional action that would otherwise be missing or combo presses.
Days Gone uses it for swiping access to different actions. Same with Killzone: Shadow Fall with drone actions
Witcher 3 - Each 4 of the various swipe directions directly opens a menu tab. Inventory, Map, etc.
Death Stranding uses one corner as dedicated photo mode button.
Works as a mouse pad in Final Fantasy 14.
And there's plenty more. But it's not going to matter how many I list or how useful they are.
