In some work environments, you are encouraged to get 40 hours a week, regardless of whether those 40 hours are necessarily put towards what are perceived as the "highest value" endeavors. So if you are blocked on everything else, why not take the remaining time and put it towards things you personally believe to be beneficial to the project? It is certainly better than sitting on your thumbs or asking people who are already busy what they think you should be doing.
