Hi
@Cong Guo, welcome to the community!
Indeed, we didn't get many requirements on this for now. Even for 3.6.0(with a refactored elastic abstraction and integration).
In practice, manually creating the listener pod is feasible if it's needed.
I referred your question to the issue of the feature, too!
