No, it has not yet been implemented neither upstream nor downstream.

I sent v5 of the patch series today [1]. Again, I would highly recommend to try and develop your solution with that API for proper integration. Otherwise, it's 100% up to you not to cause conflicts with the Proxmox VE system with your backup solution, and naturally, we cannot give you much help with development (or later with debugging user issues) of a fully separate backup stack. It would be appreciated if you could give us feedback and tell us what parts of it work and what parts might be difficult to work with for your scenario. Then we might still be able to adapt to your requirements. Adapting things retroactively means that there is less freedom to change the interface, so now is the best chance.
