I don't think it should be a "move". It would be strictly a nerf since it's free at vet 1. It would be better if nade tech unlocks AT nade at vet 0, while vet 1 still gets it for free.
best option by far i think. you could get it at any stage of the game bundled with regular nades as a nice bonus and would still be able to bypass sideteching for it if you really can't squeeze in the 100 mp / 20 (?) fu.
