The failure of the EU was to not write into (an updated version of the law) that setting a specific HTTP header means "no", and "no" means "no" not "show me a popup to ask" (i.e. showing a popup in such cases would not be allowed).
It wouldn't matter because most of the consent flows you see are already not compliant. The problem is a perpetual lack of enforcement even for the blatant breaches. An HTTP header wouldn't change the situation, websites would still ignore it and still get away with it.
