I think they would spend their time better on improving processes and removing obstacles but that almost seems a taboo to point out. I have seen tons of scrum retrospectives that got ignored as soon as the problems were outside the reach of the immediate team. In the end you can do as much estimation and reporting as you want, but things still get done by doing them, not by talking about them
