[GitHub] [airflow] uranusjr commented on issue #23942: `ALL_DONE` trigger rule not respected in TaskFlow API for upstream failures

   Since an XCom push can never be None[^1], we can probably just set the value to None in this case. Combining this with #24401, we probably need to do some additional checks in `XComArg.resolve()` to take account the current task’s trigger rule, and resolve to None when appropriate.
   
   [^1]: A design decision I didn’t agree with but that ship sailed long ago.
