But what if I don't want to become emotionally invested in the project? It would still be beneficial for the project if it were easy for me to submit bug reports (and maybe bug fixes) anyway. Emotional investment is always an option for those who want it. And a lower barrier to entry might even increase the chances of it happening anyway, even for those that started out thinking they didn't care much.
