I just looked through the headers of a request to google.com, expecting this to be wrong, but it does look like this is there! Right at the bottom, x-client-data. The value ends with == which makes me think it's some kind of hash. Crazy. It does not exist when I use ungoogled chromium, firefox, or even edge.
