I know some devs here are bullish on radicle but I cant support it or any other project funded and controlled by a shitcoin org. https://docs.radworks.org/rad-token

Looks like a very cool project. A template for the descriptor would be easy but I think you'd also need more logic around it. Probably best maintained in a lib within the anzen project along with other features needed to make a compatible bdk based wallet.
