Well, yeah, for a basic implementation, it's rather easy to track like that. What about a system where the unique id returned is based on a random value hashed with the domain name of the window? Then third party trackers would get a different id from you on each site, but your sessions would be static on the site.

True it would make it difficult to do third-party tracking across multiple sites (unless there was server-side information connecting your accounts, like an email address). And leaving aside browser fingerprinting. That could also just by achieved by disallowing third party cookies though - feels on the cusp of being a browser implementation problem (just stop allowing third party cookies).
