In the case of Star Citizen, they used to support it, but since the game is still being actively developed in the alpha stage it kept breaking. Not worth the time and money to keep fixing it, so they put it on hold. As far as I know, they still plan to support it after the main feature set is stabilized and they go into polishing mode.
But I agree, it would be great if it still/already had native support.
I’ve heard games like Elite are less problematic, since you’re sitting still and the vehicle is moving. Apparently that makes it more natural, compared to moving around on foot in the game but standing still in real life.
