Making the entirety of our current release process for Grafana public is not currently on our roadmap.
You can build from source today as you noted. That’s the foundation and functionality we provide to our team and our open source community for building and running Grafana from source.
Our release and packaging processes are, at the moment, internal to Grafana Labs. We are discussion which parts, if any, we can and should make public, but have no answers at this point in time.
