it's probably not going to happen, as "not very effective" is more early game friendly than "no effect at all". This is good for beginners, as the later may catch them off-guard.
Grass, fire and water have plenty of "not very effective", but none of them have "no effect at all", making them excellent beginners. Then addin stats, moves and other things as the game progresses, the "no effect at all" of ground, flying, ghost and normal becomes better favored as the mid-game enters approaches, and then the end game is more about the players preference than either of the two talked about here.
