Looks like a decent format for human readability, but I think the more important things once you get more than 20 or so items are (a) maintaining, (b) rearranging, and (c) querying. You have to be able to remove completed items and move open items into different places. You have to limit the tasks you are viewing to those relevant in the moment. Perhaps there is a way to use an existing system like Taskwarrior to do the querying and rearranging.
