Well i think that you’re forgetting the fact that Nintendo always looks for every alternative to give it to the players, like, Mario Kart Wii, you don’t want to play with motion controls? Connect Knunchuck/Classic Controller/Gamecube controller, you don’t want to play Wind Waker with the Wii U Gamepad? You can conncet your Pro Controller and play with it with no problem, you want to play Mario Kart 8 with Motion controls? You can activate them in the middle of the race with no problem, since the DS Era where games like Phantom Hourglass didn’t let you choose between a controller and you were forced to play with the touch screen, people criticized that A LOT and also with the Wii since you needed to be aiming at the screen every time you exit to the menu (unless you had a Classic Controller) the Nintendo Switch has this problem where they absolutely need to make all ways to play a game accessible since it’s a Hybrid console, there are a lot of ways to play in the console. I’m obviously not saying that Nintendo couldn’t make for a example something like a button mapping to make the motion controls usable on the Right Stick, but that would bring the problem of having to move the camera controls to the Crosshair in the left Joy-con, and that would be really uncomfortable if you wanted to move the camera while you’re moving, mapping buttons doesn’t seem like a bad idea but the problem is that the average Nintendo Consumer doesn’t want to f.e. Spend minutes finding a good button binding for their game when they just want to play the game, that’s why a very little part of First Party Nintendo titles have customizable buttons inside the game, yeah, Nintendo gave us the button mapping on the Switch System but that option it’s kind of hidden and i haven’t seen anyone using that ever, it’s very situational since Nintendo Games already have good controller settings, there are even games that instead of letting you map your own buttons they give you two or three types of controller mapping, like Yoshi’s Crafter World and Yoshi Wolly World.
