It actually depends on the game (engine) and how FOV is linked to resolution. The ideal situation you describe is known as "Hor+" because it widens the horizontal FOV while maintaining a constant vertical FOV when the aspect ratio of the display becomes wider. On the other hand, "Vert-" instead fixes the horizontal FOV and reduces the vertical FOV when the aspect ratio becomes wider.
Obviously, Hor+ provides a better scaling experience. Games which use Hor+ support 21:9 "out of the box" because they scale the cone of view more comfortably and realistically. Of course, if you have manual FOV controls (either through game settings, ini edits, or whatever), then this all becomes a moot point; for ultrawidescreen gaming, you should always know your target FOV and manually configure your games appropriately.
Another thing to consider for ultra-wide FOVs is that fisheye projection can help alleviate the "edges are all stretched out" effect that an ultrawide flat mapped FOV can cause. Take a look here for a good visual comparison.
