Seems like a promising area to invest in given the benefits it can provide to the users as mentioned by Shahar and Abhishek.
Abhishek also has a promising talk submitted which i am looking forward to this year at the summit. In any case, this seems to be one of the first of the very few implementations of trying to integrate Airflow officially / unofficially with an MCP server.
