This (ie. using the github issues on the repo) is great because it co-locates the mental notes breadcrumbs, the todo list and the project itself.
I use org-mode for personal project management, and by design it intermingles notes and todos. But it never fully clicked until I started putting the notes closer and closer to my repo (my workflow pre-dates github, but this approach makes me consider some modernization :))
