Do Not Track died the minute Microsoft killed any possible distinction that header provided. They may have backtracked on that dumb idea with Edge but the damage was done, the momentum of DNT was killed and they effectively "poisoned the well" and ensured that the largest portion of DNT headers seen were not in any way set by the user. The W3C abandoned it because it was already gone.
