Put differently: how do you avoid that becoming AdChoices in the browser?
One value I see is that, with machine-readable consent info, you could automate consent removal and have the browser withdraw consent for you on a regular basis by calling all those .well-knowns.
But then… why not do that sooner and signal that withdrawal at the source? :)
