My experience with work is that everything can be slightly improved all the time. You have to stop at a certain point and I think the author has found the nicest place to stop, at least for employee happiness. On the other side, if you have been working on something alone, I think it is a clever idea to accept the feedback of your boss just to have another perspective.
