Federation in Gitlab - NLNet grant proposal maybe? (December 2022)

If by spec you mean forgefed, it is still in flux.

Vervis and Forgejo is likely to be the next one in a few months.

@fr33domlover is the one working on this and will be able to comment.

In the context of GitLab it is likely too much and IMHO you should not worry about moderation.

It’s a little short indeed. I would be happy to provide you with a recommendation.
