[GitHub] [airflow] uranusjr commented on issue #16371: Make `XCom.get_one()` + `get_many()` accept run_id

   Similar to how we plan to associate `TaskInstance` to `DagRun` via `run_id` (instead of implicitly via `execution_date`), would it make sense to also add a `run_id` column on XCom as well? That (plus backfilled values) would make this a lot easier; currently since XCom only has `dag_id` and `execution_date`, we need to do an SQL join to filter with `run_id`.
