Note after doing more research. This kind-of already exists too, Google open-sourced the implementation they made for Sparkasse, per the announcement (#1022044) from 10 days ago.
Per response to an issue on the repo, about a quarter of it is alleged to be stable, some stuff is explicitly not (ligero, sumcheck).
Now I wonder, what can we do? Provide an open end-to-end implementation?
