Does John have to go over at WrestleMania

For me yes because not only does Cena break Ric Flair's record to become a 17 time World Champion but if you really want to solidify John as a heel and make this heel turn stick, then John has to go over.

But then if you have Cody go over, it is basically a passing of the torch. Cody is already the face of our company and by having him beat yet another GOAT in Cena after he dethroned Roman last year at WrestleMania, then it puts Cody even further into that upper echelon towards being an all time great.
