Aymeric, are you sure about that? I can't find the code, and the docs for current_app say it's noto set by Django itself: https://docs.djangoproject.com/en/2.2/ref/request-response/#django.http.HttpRequest.current_app
Also middleware can't reliably make use of routing information except in process_view, because if another middleware changes request.urlconf, it will be "re-routed".
