I for one would like to see official joystick support as well. Where xinput covers mainly gamepads, there are still lots of devices for more niche genres that are not supported. Current implementation leaves out for example almost all steering wheels, flight sticks and other sim related controllers.
I’m aware of the plugins out there but they need to be constantly updated and some of them have major issues that have never been solved. I feel that these kind of things take devs efforts away from developing their games as they have to implement/fix things that engine should provide them.
