I'm not sure I've ever understood the point of this. Aren't all cookies trivially "any-party" cookies? Can't any form of persistence be used to track a user? 3rd-party cookies as they exist today just give a path of least resistance so that most of that behavior is implemented the same way. Consistent implementation allows the user a simple way to block that behavior.
