Review Comment:
I just checked and indeed this function is only used in `views.py`. However
since there’s no way to tell whether it’s also used by user code somewhere
(backward compatibility concerns), it’s probably better to make the function
signature something like this:
```python
def get_dag_run_conf(
dag_run_conf: Any,
*,
json_encoder: Type[json.JSONEncoder] = json.JSONEncoder,
) -> tuple[str | None, bool]:
...
```
and we can move `DagRunConfEncoder` to `vies.py` as a private class.
