What makes you more trackable is whether you are one of the small
minority of users to change the default setting. :) Especially when
intersected with screen size, timezone, system fonts.... [1] But
really, compared to all the different forms of supercookies nowadays
(localstorage, IndexedDB, WebSQL, HSTS), it is probably not a big deal.

What's more important is that we're fed up with advertising companies
tracking our users. We're going to use technical measures to prevent
that, and they're going to be opt-out, not opt-in. The DNT header is
just the start!
