Those photos are indexed by Google and contain my name, even if I have chosen not to share photos I've been tagged in. I want to be able to see the list of public ones so that I can manually untag myself. Similarly, it would take too long for someone with thousands of wall posts to find the ones that might have accidentally been set to "everyone".
I think that it might have been better to wait until these were included before officially launching the tool, because the photo issue affects almost everyone on Facebook, and if people use this tool and everything checks out ok, they probably won't return again if you update it later.
