For tracking uniques, why can’t we just set a “first_visit=false” cookie if not present on first request? The number of new unique users is then the number of requests that came in without that cookie in whatever time window. Expiration timeline left as an exercise for the reader (month, week, whatever).

This zero-entropy cookie cannot be linked to a specific person and would not require consent under any privacy law I think.
