Hi John! Yes, IMO, making it MUST, doesn't require new text. Saying SHOULD means there is additional behavior to cover with mitigation guidance. I leave it to the WG to determine the right approach. Personally, I agree with your intuition, if someone wants to extend this work they can update it more formally to relax the constraints.
