I would also question these examples as genuine "universal" solutions. it might work for some, but I'm quite sure not for everybody (hence why it shouldn't be a standard).
A lot of people do prefer having pedals far from each other for various reasons (eg avoid stomping on 2 pedals at the same time, to control pedals with both feet, etc.).
Not always easy and cheap, but there are solutions that allow to hide pedals and have a multi-pedal/router/matrix to control them all.
I'm not trying to say that is neither a standard nor the perfect solution, but it's a solution.
