Maybe they want The End to not be the Minecraft dimension... but rather to be taken as the moment when you decide to stop playing the game, when you put yourself a limit, when you'll stop pursuing goals... and there will it be, "The End"... you, the player, will have to find some other way to use your time and move on from what you once considered a way to spend your time trough out minutes, hours and probably... days, the ones where you were waiting for The End to come, and many other things, trees, minerals, mobs... all excited of course, but then realize that time when you would get excited is over, and maybe then you'll find out what The End symbolized all along...
