I can’t help but notice most (all I’ve seen anyway) of the federated projects are hosted on GitHub. GitLab is also not federated, but can be self hosted and has at least discussed it.
I am fully aware of my bias for GitLab over GitHub, but I still wonder why is those things? Is there a federated source hosting project?
I would like to add that git is a pretty good example of data people have backups for. I don’t care if Github blows up tomorrow because I have repos on my disk. Even if my disk also dies, my friends have my repos cloned so I wouldn’t lose much
