Hello rah,
As mentioned in multiple posts around the forum, we are currently working at the new v2, which is basically a rewrite of the whole system. Because of that, and also to avoid further pressures, we are bringing the development forward on private repositories, at least until the first alpha version will be out. Unfortunately we are working at a slow pace - our free time is low, life happens - but we are close to a first release.
I agree with you that we should be more transparent with the roadmap and to be better structured for collaboration. I don't know if the typical model you described is applicable here because there's a clear break between v1 and v2, so we decided to work on separate repos.
If you think you could help us on the OS side for this first v2 release, please PM me.
