Crab, the research clearly needs to be done to focus on RW, and, based on what you and ShyTorque have said, it sounds like there is an opportunity for a more flexible approach to be applied to RW.
We need someone to fund the research though. Neither ICAO nor the CAA have the money. That means either a university with a research grant (and many of their sources of cash dried up when we left the EU) or business; BHA?
