That's like a tiny bandaid; in the next iteration they'll copy the A/AAAA records instead of CNAMEing them; that would make CNAME uncloaking useless _and_ save one DNS roundtrip reducing browser latency.
Without using CNAMEs the third party tracker IP addresses would be less dynamic making them easier to block with a firewall.
