The protocol extension is ForgeFed and it’s still a work in progress afaik

The issue tracker is on Codeberg.

Forgejo is only one of the implementations and not the reference implementation.

It will also be more general:

• general VCS repo support and not just git
• patch tracker (merge requests)
• ticket tracker (issues)
• release tracker
• separation of repo and trackers, which allows for them to be on different instances and have specialized implementations
• roadmap and workflow for issues and MR
