Example:
https://github.com/apache/airflow/actions/runs/15701027598/job/44236593865
- The Operator type is defined in `airflow.sdk.types`
- The actual AbstractOperator class is in
`airflow.sdk.definitions._internal.abstractoperator`
- When we try to import Operator from `_internal.abstractoperator`, mypy
fails, likely becausE:
- It's looking for a type definition that doesn't exist there
- The class AbstractOperator exists there, but not the Operator type
When we import from the non-existent
`airflow.sdk.definitions.abstractoperator`, mypy somehow works, probably
because:
- It's likely falling back to the original type definition in types.py
- This is probably a mypy bug or unexpected behavior
This is a case where mypy's behavior is masking a problem - it's accepting
an import from a non-existent path, which is not what we want.
