Wow, two whole pages PKJ genuinely thought would satisfy fans!
Having a "Superfamily" moment doesn't justify not de-aging and making him a kid again. All it shows is that DC knows exactly what fans want and are very capable of delivering, but they adamantly refuse to because...they still haven't explained. All we have is speculation that DC wants to make Jon into Superbro 2.0 because those in power genuinely believe Superman is unrelatable and not relevant anymore.
