I once worked in a shop where a few teams made blanket rules for clubs of reviewers for different core technologies. There was a Python reviewers group a Puppet reviewers group etc. The membership of these groups bore little resemblance on the technologies people used and had to work in day to day, but instead reflecting the current group politics of a large engineering organization. As the reviewer enforcement was wired into the deployment tool - appeasing these reviewers was required to be productive. In practice the reviewers would road block entire team's initiatives. The end result was a proliferation of technologies across the company such that teams could practice team code review rather than adhere to the wims of the anointed reviewers.
