It's not really clear to me how much discussion is needed... if one assumes that you're just considering a HTTP header field, then the only technical question I can think of is whether there's intended to be some level of richness of expressivity vs. a boolean signal "don't sell my data". At that point it is mostly a matter of writing down the expected semantics (the header field registry requires only Expert Review for allocations). -Ben
