Apple (Webkit) has proposed a browser feature that would allow tracking ad click-to-conversion without tracking the user or click. It involves the browser phoning home with low-entropy identifiers. https://webkit.org/blog/11529/introducing-private-click-measurement-pcm/ https://webkit.org/blog/11529/introducing-private-click-meas... From a pure privacy perspective, it's odd because it involves the browser collaborating in measuring the results of your behavior. I think it shares several of the concerns with Google's FLoC and "privacy sandbox" proposals. It only makes sense if you buy into Apple's perspective that there's a level of "acceptable" tracking, and new tracking features under that threshold are acceptable if they give Apple the political capital to kill tracking technology that crosses that threshold. It's a bit much to swallow. But they are at least trying to address that concern.
