While I like the idea, a potential problem comes to mind. A list of what domains are tracking domains will need to be maintained. The need to maintain that list will possibly move the cat-and-mouse game of ads vs ad-blockers to the tracking list as well. I could totally see Alphabet paying Mozilla to remove analytics.google.com from the tracking domain list (because "it's just analytics; it doesn't track you or infringe on your privacy at all") similar to advertisers paying to be on Adblock Plus' "Acceptable Ads" list.
