It is not a work around in the sense that they will be able to track you, they won't. What Google tells them that if they use Analytics 4, they can use modelling to give attribution of convertion. In this case, attribution means not fingerprinting but percentage of people that was converted thanks to Ads. For other analytic engines they set the fields as 'not set'. They day that in their models they aggregate data as geo, IP, and others and they won't give the fingerprinting data. The only problem is that they don't give details on the privacy preservation of their ML models. This means that if they fuck it up and give to much information, someone could try to reverse the aggregation (like doing a deconvolution) and do some fingerprinting.
