You assume that this would still be possible given the issue. You also assume that SE is just making this decision facetiously. Chances are very strong that they tried to make it a normal class and could not make it work within the game.
To Sum this up:
People tell SE " WE WANT AN OREO ICECREAM CAKE THAT DOESNT MELT, thats all we want!!!"
SE says "Hmm ok, we can give you an OREO ICECREAM CAKE, but it might melt if you dont eat it quick, or we can give you a regular plain cake that has an oreo on top of it, but it wont melt!"
A lot of you are saying that youll take the second cake on the simple basis it wont melt. SE is offering you what your asking for, as closely as possible, and you are rejecting it for an imitation. Or bluntly, youre more concerned with your cake not melting than having the cake you say desire.
