While I'm all for having DNT's default set to ON, how much does it really change?

Is there really any impetus for companies to not track you when you send a DNT header? Is there really any governing body that enforces it in any meaningful way?

I can imagine a release of a plugin similar to Privacy Badger or Ghostery that whitelists sites that honor DNT and follow a reasonable privacy policy. I'd use it.

This may seem paradoxical, in that this plugin would only work correctly by not sending DNT to those sites.

But I've found that some tracking cookies are useful (the one for editing Wikimedia projects, for example), and sites should be able to earn their way onto a whitelist, as long as they honor the requests of people who say "No. Don't track me. Not even you."
