Creepers and the flame enchant

Personally, I feel that it's a lack of continuity that creepers don't light when set on fire by an enchant. In the same way that using a flint and steel on a creeper it explodes, creepers should light when using a flame bow, or fire aspect. It simply makes sense. I think this would be a great addition and would really make sense in-game. if you shoot TNT with a flame bow, it lights, so if you shoot a creeper it should do the same thing.
