Actually, I suspect this is extremely low-complexity! All the info is right there in the database, and just needs to be displayed in a basic form. I think you're probably right about "low impact" though -- or at least, "low utility", since it might have a large impact on support load if done wrong. Not that that's a vote against it, mind you ;) I'd find it faintly useful/interesting and I suspect quite a few others would too. It's just not something I can see people clamouring for.
