Hi Christophe,
You can still map the segments that you created for PBD to a custom export destination to get a list of hashed email ID's and their corresponding segments they qualified for. You can contact AAM support to get a custom server to server destination provisioned.
The only fallback with this approach is you will get only the batch data and file will be exported once a day, whereas PBD destinations support both types of activation: real time and batch.
Thanks,
