    <p>Hello,</p>
    <p>as far as I am aware, the lowest possible level you can
      (officially) reach with the policy files is project-level not
      user-level. Some APIs still provide user-level checks but those
      are a thing from the past and effectively deprecated. Nova API was
      migrated to Oslo Policies for API 2.1 where the user-level was
      removed entirely from the policy implementation, if I recall
      correctly.<br>
    </p>
    <p>Kind regards,</p>
