I disagree - although it's possible that a person of size might fail one or more of the section 121.585 criteria you included on your list - it's not a given that they would fail - as none of the items you listed from the regulation are impossible for a person of size to accomplish.
In any event, worrying about the size of the exit row occupants has gotta be one of the more useless exercises; in the extremely unlikely event that there's a survivable disaster necessitating a speedy evacuation, the size or shape of the exit row occupants isn't gonna matter.
