Honest question: Banning pick intentions

So for the most part, suggestions about how to "fix" Riot's systems are just bad. LP loss forgiveness for somebody "feeding" on your team is a popular suggestion with tons of potential for abuse, for example. "Potential for abuse" tends to be the mitigating factor for all sorts of issues. That's probably why the Remake system is so narrow, for example.

But has Riot ever commented on the ability for players to ban their teammates' own draft intentions? The best case for allowing it to happen that I can come up with is that a champ is at a pick-or-ban power level and a teammate is trying to last-pick it, but that's super narrow and still highly debatable. As far as I can tell, the two main reasons for banning your own teammate's pick are to directly troll them or because you weren't paying attention. Neither seem like they should be allowed.
