Are they active contributors as part of that department - or despite also being there?
My understanding is that that department has contributed 0 lines of code. Correct me if you have better numbers...
The task of the leadership committee isn't writing code, so that's a pretty useless metric to evaluate it against unless you can't imagine anything worth doing in open-source that isn't code. That it's formed from active contributors is important though, because it means they don't need to make "busywork" to be relevant.
The fact that you are good at writing or reviewing code doesn't mean you are a good judge or moderator.
