The issues they want to address are already solved in Diversion (https://diversion.dev). Granted it's not open source yet, but that isn't usually a priority for game/entertainment studios - having a complete platform is.

After tearing it apart for 2 hours - it seems like a solid beginning, but definitely not a fully-functioning product (especially on Mac, I hope it works better on Linux/Windows).
