Codemod: no-csrf-exempt decorator Semgrep

    ❯❱ python.django.security.audit.csrf-exempt.no-csrf-exempt
          Detected usage of @csrf_exempt, which indicates that there is no CSRF token set for this route. This
          could lead to an attacker manipulating the user's account and exfiltration of private data. Instead,
          create a function without this decorator.

The codemod here would be to remove the decorator, however, there are legitimate reasons to use this decorator some times. So do we want to create this codemod but make it merge after review?
