You might be interested in taking a look at PullApprove (https://pullapprove.com/) -- basically you put a YAML in your repo that defines what code review looks like for your team (who, when, how many need to approve, etc. -- http://docs.pullapprove.com/). Approval/rejection can then be triggered by PR comments and it uses the status API so you know when the PR has passed review.

Code review "rules" can get pretty complicated since everyone works a little differently...not sure if GitHub will ever try to tackle that or not but we've got a lot of customers who are happy with how PullApprove fills the gap.

That looks great, I'll suggest that we start using it.
