That's the part I do not really get. It already is an addon, kind of. They introduced the concept of system addons, that are addons code wise, but can't be managed via the addon interface, and that is what Hello was already. This bugreport however seems to be about removing that system addon. Maybe they want to transform it into a regular addon. But the bugreport does not mention it, and I saw no additional explication elsewhere.
