I suspect some of these slimy outcomes (parties and offices having special access to request review) are pretty hard to avoid in practice. Like, if you know for a fact that there will be illegal actors targeting both campaigns, do you not listen to direct requests from the targets? And if you offer it to one side, would you offer it to all? I bet there are more principled ways to do it but I also think this is what it would like if a reasonably well intentioned but also selfish / risk averse staff tried to react in realtime to a really new situation.
