Forgive the strange question, but what is this draft hoping to accomplish? IIUC it's basically DEX but with the details left to out-of-band communication rather than a header. So is the intent simply to inform people that this control-plane approach is something that is happening in the Internet, and give some advice on how to do it? Or this meant to inform a future standardization effort?
