I can't speak to any precedence for using a draft requirement; it may have happened but it's probably rare. If it has happened, it may not help you here because it's the kind of situation where you'd have to demonstrate that you're using an appropriate path on its merits.Since this is a design credit, I would suggest submitting this an an alternative compliance path, being sure to justify why your project wants to pursue this path instead of the standard one. If it gets rejected during the design review, you then have time to re-submit with better documentation, or with the standard path.
