Hi, I have a question regarding kwargs usage in BaseOperator( https://github.com/apache/incubator-airflow/blob/master/airflow/models.py#L2306-L2315). Since this pr(https://github.com/apache/incubator-airflow/pull/1285) checked in, airflow turns on deprecation warning by default. And per the comment, the community plans to remove kwargs usage in airflow 2.0.
I wonder whether we still have the plan to remove kwargs in airflow 2.0(do we have the timeline for airflow 2.0?) as the warning generates too many noises for our internal production env as well as the travis CI log. Thanks, -Tao
