It seems to me that every year we get asked here on meta whether we want hats on main. See 'Tis the season to be... and How are we protecting our heads this year? With Hats! and Would you like some hats? Yes, please!. So I was surprised to get a hat earlier today, without having seen the annual discussion of whether we wanted them, how to opt out, etc.
Did I miss it? or was it just decided somewhere that since we've had them three years running, we must all want them?
