In fact this "key" parameter is used and removed by the "init_app"
decorator which receives the calls (with key) before pasing them to
the real params() function (without key). So my understanding is that
pylint does not handle the function signature changes by a decorator,
and it seems confirmed by a message on the pylint mailing-list:
