The move that decided the main event of WrestleMania has to be forgotten. Why? PR issues. It's just too violent looking a move to be seen in WWE apparently. Seth Rollins himself explained this to Fox Sports last year:
It was a decision that was collectively made from a PR standpoint. Curb stomp just seemed like it was too perceptually violent, I guess you would say. I never hurt anyone with it. It was just something we didnt want kids trying on each other.
That's why every montage you see of the main event cuts away before The Architect hits the move on Roman Reigns, before showing the three count that ended the match. The only way you'll see another Curb Stomp in a WWE ring is by re-watching the unedited main event on your WWE Network.
