GitHub user pykenny edited a comment on the discussion: Dynamic mapped tasks 
group arguments are interpreted as MappedArgument when provided to classic 
operators

Earlier I shared my 
[thoughts](https://github.com/apache/airflow/discussions/40728#discussioncomment-12100714)
 on the reply thread, and I think this kind of confusion on writing decorated 
task group often happens because unlike tasks, task groups are just a set of 
layered prefixes attached to task ID mainly used for filtering task subset out 
from a DAG, instead of a task-like entity having relation with all its 
underlying task entities. And that's also why XComs/TaskFlow only work on task 
level, but not for task groups.

Making the proposed case work implies redesigning DAG model is needed, in order 
to make XCom communication possible on task groups.
