I'm always happy when I finish something, and I think it's more about quantity instead of quality in this case, so I agree that it's a bit unnecessary. I like the idea, because it causes me to reflect on what I have done, yet it never ends up helping me. It could work, the execution is just a bit wrong, so I agree that if enough people want it gone it should either be removed or be optional/have a checkbox on your profile or something.
