Is this what we want?

One more question: If I increase the number of required reviewers to 2, does that mean both have to have the Reviewer role? If so, this won't be nearly as useful to us on the openjfx project. I suspect the same is true of many sub-projects in the JDK itself. For example, the policy in the client team is that fixes in general need 2 reviewers, at least one of which must be a "R" reviewer. OpenJFX has a similar policy (except that only "high-impact" fixes need a second reviewer) in that one one of the reviewers needs to be a "R" reviewer.
