I think Sasha's point is important. You have a valid argument that few applied despite your outreach and effort. However, is it possible within the current procedures to find out the reasons they didn't apply? Did they get the communications? Do they not have enough resources and time to take part? Do they know and understand the importance of the role? And so on. If we can find out the reasons they didn't apply and if the issues they mention can be solved with some preparation (not impractical solutions though!), then you can prepare for the next Nomcom with additional insights.
as you and sasha seem to be focused on this, it would be cool if you did the research and reported back. i think daniel is busy enough right now. having the results of your research, when we do the post-process review after all this is done, would be extremely helpful to guide us next time. randy
