Really looking forward to the federation, hosting Forgejo for my own stuff while having discoverability/issue tracking with other instances would be the best of both worlds. As of now I'm mirroring stuff across self-hosted forgejo/github.com/gitlab.com where the forgejo instance is just part of my self-hosting hobby and not "load bearing".

I think that Gitlab Cells[1] might go into the same direction, there is a mention of federation in the design document.
