It was one of those things that was repeated ad nauseam in the N52 days as far as I can tell a rebuff to the more golden age angle they were going for back then. Which I always find funny given that Post-Crisis went out of it's way to ditch the loser Kent schtick and gave him the Mr.Popularity angle.
Imo while it's very clear there's nothing cool about modern Superman at the very least Golden Age Superman had elements that people found admirable and still try to emulate.
