1 thing, the reason why is because of abuse, not saying any staff would abuse it but you always get that one player that manipulates staff and trys to get stuff plus /enchant gives you any enchant (can someone say "god armor") /give, just no point to it, just have creative and you can get non legit blocks (the ones not in creative) and experience with not having those commands i can say it doesnt take that much time, it takes the same amount of time to do it as it takes to type it out, plus im not sure if those are "Op" commands and if they are then there is another reason handing out op to staff, not trying to be mean to staff or anyone, just stating my opinion.
