Team Disablefears modification

So I have been playing Minecraft for a while now and I noticed that villagers are afraid of zombies, even if they are in the same team. They run away from them even while the zombies are not attacking them! It makes no sense and I really would like it if it would change. I would just like to be able to run the command /team modify <team> disablefears true. Please add this in the next update.
