That may be a sign that something like Dunbar's number is at work limiting group sizes. Crunching Gerrit approver group membership counts across 566 official Git repos (those belonging to a TC recognized project team), 90% have 17 or fewer accounts capable of approving changes. Below that there's a pretty varied spread (with 23% of repos having only 1 approver). This is a pretty raw analysis though, so something taking into account how many of those reviewers regularly exercised their approval access may yield different insights entirely. -- Jeremy Stanley
