New world (after the end)

Kinda far fetched but i think that there should be another world after defeating the ender dragon and obtaining an elytra and the dragons egg. This is because right now I think a lot of people that play minecraft just to complete it which i understand because there no reward for them to continue. But it would be nice to see players continue after the end and this could be done by a ritual of some sorts where the player sacrifices the dragon egg(after ritual is complete they gain dragon egg shells for a trophy to replace the dragon egg) and in this world everything is different, it could also serve as a world purely for the community and their most popular ideas andl it is optional to go to this next world where the player starts ane.
