If you put all G-services in their own container, google.com/mail can't access google.com/maps cookies, so, will it also not track location. Not sure actually, they indeed probably store your "consent" on their server. Could you block location services per container perhaps?
Hmm this is a smart move indeed, all of a sudden I'm logged into G-maps whereas I wasn't before... FireFox helpfully opened google.com/maps in my Google container...
