How would that solve anything? The comment you are replying to doesn't want to be asked for permission for cookies. The commentor wants all the cookie requests to be accepted automatically.
He's suggesting making the decision once, per-browser, not per-website, whether or not to allow cookies. Then the browser can include this information in the HTTP header, so the website never needs to ask you.
Oh, Ok. I initially read it as the browsers should ask the user whenever they send personally identifying info, which is basically the status quo. Thanks for correcting me.
