Ultrawide is a different thing - you have to adjust camera parameters to make it work good. Frame Rate adjustments also depend on the Game Engine - there are probably still a lot of games out there that link physics with frame rate (especially on consoles), so just ramping up FPS will break your game. This can be avoided if you have code you can actually modify.
I am sure that manual de/recompilations are easier to modify, but it’s also more work - not a bit more work, but years of work in many cases.
