I have so many questions that I'm sure will be cleared up over time. I am very happy to hear this "classification" happens on-device. I am curious how opaque it is. I assume, like the rest of WebKit the classifier is open source? In Safari, both desktop and mobile, is there a way to see which domains/cookies are blocked/purged or what the time remaining on them is (assuming I don't revisit the page)? Also, I assume this can easily be beaten be smart ad networks. "Hey, publisher, just use our JS snippet which loads your first-party cookie we may have set previously and then loads a JS URL with that identifier as a query param in the URL along with other fingerprinting info, and we may set that first-party cookie after load too." I would personally love the option to not send any third party cookies not on the same domain as the frame (or maybe an opt-in) on a per-site basis as I can only see it breaking social logins and other lazily-dev'd items like comment board integration (most SSO uses redirects anyways). Surely if a website wanted to offer its own domain's cookie store, it could (just like you can with local storage).
