That's all well and good, but even a halfway engaged PM is going to play with the product while it's in development, and they will tell you about what they discover along the way. It may not strictly be their job but they're going to do it. If a tool exists to help them capture more information that makes their inevitable reports more useful, is that a bad thing?
There is a nuance here: those reports from management should go to QA, not to developers. If QA can't transform manager report into a proper bug report, then it's not worth anything. Also, QA will have time to verify the fix, unlike managers.
