Look at this. The achievements involving the Wither branch off of the ones about the Enderdragon! Great, but what if we want to kill the Wither first? Take a look at that again- what if the achievements for the Wither were to come off of "Into Fire" instead? That way, players can choose which to fight first!

I'll admit that I just accidentally got 3 Wither Skulls trying to escape a Nether Fortress… I don't want to keep them on Armor Stands forever!
