Indeed. I think the most interesting and worthwhile reporting hinges on having pretty rich metadata attached to the tickets, so you can answer questions like how many man-hours did feature X take? how much over the estimate was that? how consistent is that compared with prior similar features? stacking up the critical path from now until release, and given the present estimates and past history, what timeframe are we looking at? But to really get anywhere with that you need everyone to have put in the required metadata, to be correctly linking tickets that block each other, to be providing estimates upfront and tracking time, to be accurately capturing the work in tickets. You also need people not to be sandbagging and then using the "extra" time to perform localized refactors and other cleanup that they can't otherwise get buy-in for.
