What's the use of archived projects?

For me, it would only make sense to re-visit archived projects, if I could see all completed tasks. This is not the case, though - if I archive a project and have unfinished tasks left, I can only see those. In order to better evaluate a project, it would only make sense to get the full picture.

For example: I'm moving homes and I have a project with lots of different tasks. New tasks are added every day, others get completed. After the move is done, I will eventually archive this project. If I should ever move house again, I would like to go back to this project and see all the things I did etc. Of course, I know that I can also save templates, but these are only like "snapshots" at a certain time.

Having an easy way to go back into an archived project and see all the tasks (completed and open) would be way better. Or am I missing something?
