yes, client hints.

google "has access to all this data" in exactly the same way any other website does. you request the information you need from the client, and the client can choose to provide it or not. clients provide it by default.

hate on google all you want, but UA reduction is objectively a good thing. "my friend jacob wants to slurp up everything from the user-agent string on the first request" is not a good argument.
