There is another fundamental issue with pools in airflow that this would help solve: if you use pools to limit concurrency across different DAGs you [lose the ability to prioritise one task above another in the same DAG](https://stackoverflow.com/questions/66779968/how-does-task-priority-work-in-airflow-when-both-pools-and-dag-concurrency-are-u), which may have a concurrency limit on it. This is because the `priority_weight` argument for the operator refers to priority within a pool not a DAG. If we could add tasks to more than one pool, you could then have each task in a pool for the DAG and another pool for limiting concurrency with a task in seperate DAG which shares a resource. -- This is an automated message from the Apache Git Service.
