But I disagree that it was ever "Barry Allen created the speed force" until now.
The closest was an old story, predating Waid coming up with the Speed Force, where he became the lightning bolt that went back in time to give himself powers. But since that origin also had Barry as a Reed Richardsesque superscientist that proved Tachyons exist, and the "lightningbolt" talked to Barry and got his permission before hitting him, I call shenanigans on pointing to that story as justifying this one.
