This is a really interesting read. Thanks. I have found in my own experience that developers tend to include the same people over and over again in their PRs and what ends up happening is people tend to just "trust" what the submitter has committed. This often leads to PRs that are almost blindly approved. By involving management to keep the PRs as a tool for discussion (social and technical), I think this could be avoided. It's probably also a good idea to mix up the reviewers (a healthy mix of people familiar with the code and those not familiar with it).
