Not really. I suppose the Data Working Group is the closest thing to this concept. That consists of about 20 people to cover the entire world - also unpaid volunteers like other contributors. Clearly 20 people don’t check every tag added to every object - they rely mainly on mappers bringing possible issues to their attention. And most of their work doesn’t rely on any special rights, with a few exceptions described on the linked page.
