Currently the security-only branches are set so that only release managers
can merge PRs since they technically are on the hook if some compatibility
breaks due to some patch (e.g. I expect Ned to use this for 3.7 once we hit
rc to really control what goes in last minute). It's easy enough to turn
this protection off, though, if people want.
