Is Cenas ultimate heel move NOT winning #17 at Wrestlemania?

So after watching his promo from Raw, alot of people in the comments were saying him keeping his theme music and attire the same is the ultimate heel move bc the fans wanted to see a 'heel johm cena' theme and attire. Well it made me wonder, since he is going this direction with trying to disappoint the fans as much as he can with stuff like "YOU GET NOTHING", what if his ulitmate heel move is NOT winning his record breaking 17th championship at Mania. Cuz i feel thats what everyone wants to see.

Do you think he would put his "heel gimmick" of letting the fans down and no longer giving them what they want ahead of his "legacy" and the chance to have a recoed breaking achievement?
