If all my open problems could be localized in a single place in the codebase, I might indeed keep all my todo items as comments. But sometimes they span a lot of the code. The organizing principle of the todo document is problems. The organizing principle of the code is something else -- control, data. Perhaps ideally they would align, but in my experience they don't.
