I don't think this is very informed by actually going to hackathons. A good team project needs a strong vision and someone that coordinates that vision among team members. Its hard to coordinate that vision AND directly contribute at the same time in a compressed time period (I've tried to do that too and its really hard) There are a lot more people who would want that kind of role than people who would be good at it/able to attract a team for it. But that doesn't mean that that role isn't important for team projects.
