Are there any, or can we maybe come up with (i.e. suggestions please if it seems like a good idea), HTTP headers that browsers can send to sites that automatically instruct them in terms of:1. The kinds of cookies I'm willing to accept (e.g. strictly necessary). For example, `X-Prefer-Cookies: strictly-necessary` or `X-Prefer-Cookies: all`.2. The fact that I don't, and probably never will, care about your newsletter. (If your content really interests me, I'll find a way through your UI to subscribe.) For example: `X-Offer-Newsletter: no`, or `X-Offer-Newsletter: yes`.If you wanted to facilitate more general UX preference indications from the client side, you could potentially come up with a scheme like `X-UX-Preferences: strictly-necessary-cookies; no-newsletters`.This way I can set these preferences once in my browser and be done with your annoying cookie selection and newsletter popups (if your site honours those headers, of course).I think that, if most websites honoured those headers, it might just fix 80% of what I personally feel is wrong with the modern web. (The other 20% I think involves completely eradicating online advertising-driven business models from the face of the planet, which I think is quite a bit harder to achieve than this.)EDIT: grammar
