Because that is how it would happen in practice if it was done by WotC.Classes are easy to remove. All it takes is some scissors and determination and you can remove any class from the PHB you want. Nothing else necessary. Especially no need to redesign them as subclasses. Flat out removing classes vs redesigning some into subclasses are 2 different things. Why are you confounding the 2?
