Variant Human was allowed, but bad grammar was not 
Actually, for both my campaigns I seriously considered banning the base human. I don't like how much it changes the meta of character creation. If you use the array, it's absolutely terrible, because you'll end up with 4 odd ability scores. If you use point buy, it's easy to optimize by making all your ability scores even. If you roll (which is my group's preferred option), it becomes the default race if you roll 4+ odd ability scores, regardless of what you originally wanted to do. Since I use feats, I feel the variant Human does a better job of showing human's versatility and variability.
