> This would be a valid way of thinking about it, but programmers aren't generally judged on their meeting attendance but rather their code output.

Not universally. Programmers are judged by overall success or failure of the project they are working on. And those ones who can take credit for a success or who can effectively deflect blame for failure are the ones who got promoted. Being in the meetings with the decision makers provides the forum for self-promotion and controlling the message. This does not always mean that they did most of the work. More code or less code is unfortunately secondary.
