I have seen the @Codeberg people say they don't want to be the only code-forge.

I.e., they don't wan to replace GitHub. They want there to be many code-forges out there, including them.

I agree with this goal.

But — I think until we (at least) have federated pull-requests, this is less likely to happen.

And, I do know that there is an effort to add ActivityPub support to Forgejo, Gitea, and others.

I think ForgeFed is important for this goal
