The suitable initial group seems clear enough: every administrator.
Beyond that, the censored log should be available to everyone. Administrators often have more than enough to do and any assistance non-administrators can do in the way of oversight is a good thing.
Removing the page isn't close to sufficient - it conceals what is perhaps the most significant part of what is being overseen: who is doing what, where and still concealed from most, why.
It's worth remembering that a few million pages with things not vanishing completely have not brought the encyclopedia or Foundation down. Making sure we have ample oversight so that people actually look hard at what is being done and mention problems is important to our process.
Without broad oversight, the capability to make thing silently vanish should also be vanishing.
