When you want to make sure that across all sites cookies should never be used. It's otherwise incredibly difficult to ensure all sites implement it correctly.

What this feature would do is

• Define a custom tracker.js in the plugin that makes ideally sure that cookies cannot be enabled in the client (eg we can overwrite some tracker methods like tracker.setCookieConsentGiven=function(){} etc and we can automatically call tracker.disableCookies())
• Server side we would in Tracker/Request never return any visitorId. So even if the client did send a visitorId, we would ignore it and rely on fingerprint.

Out of scope for now be removing metrics like Unique visitors that wouldn't be correct anymore.
