Yeah, right, I was not specific enough on this one. It'll definitely go beyond GitHub, extending to some other git solutions, but we don't have a decision whether it's "any" public repo or public repo hosted on the service from some list (like, GitHub, GitLab, Gitee, etc.) We'll look into it later on.
gitlab.gnome.org - I'd expect it to be all open source, right? Open source program should cover such cases.
