I doubt that. What I think we'll see is that the content producers will inline the ad-industry adverts & tracking code and send the tracking data back to them. Which amounts to routing the advertising machinery through the content producer's network rather than directly to the client. I don't see where the vetting process will be vastly improved or how it would lead to fewer trackers.

You can't get a tracking code that tracks users across all the sites they visit unless the user gets their tracking from a single site.

The best thing the tracking industry _could_ have done is not pair it with stuff you don't want to view like adverts. If tracking was done via jquery hosted on a CDN, it's quite feasible we wouldn't even know it was happening.

That almost certainly is being done, and we probably know about it.

Surely google track their cdns?

If they do, they aren't using tracking cookies. I can't guarantee they aren't doing any sneaky browser fingerprinting (like panopticlick.eff.org) to track me, though.
