Google on the server side can see that you are using incognito. It could choose not to track you out of respect for the choice it knows you made. It instead does the exact opposite.

No, that's the whole point, Google on the server-side (or any other server-side components) shouldn't be able to know you're in Incognito. Chrome already goes to great lengths to try to hide the fact you're in Incognito to servers, because many servers try to block content if they could detect you're in Incognito.
So the only other option would be to only let Google server-side services know you're Incognito, and that actually would be a gross violation of privacy.
