The end goal of this proposal is to build interoperability features into GitLab so that it’s possible on one instance of GitLab to open a merge request to a project hosted on an other instance, merging all willing instances in a global network.
To achieve that, we propose to use ActivityPub, the w3c standard used by the Fediverse. This will allow us to build upon a robust and battle-tested protocol, and it will open GitLab to a wider community.
He’s saying Git is already decentralized, GitLab isn’t.
A project using mailing lists for development can already receive patches from (pretty much) any mail server (while still having a central Git repo).
It’s kinda surprising it took this long for this to come to Git “forges” TBH.
