Hi Jihoon Son,

Thank you very much for this list of questions. The following is my personal 
understanding.

1. What is the current status of the project?

Helm has undergone a major version upgrade. Helm3 will continue to be 
maintained, but Helm2 will no longer be maintained, and the Helm Chart related 
to the Apache project is no longer maintained in Helm3. It is recommended to 
maintain it in their respective Apache projects.

2. Does it reflect the most recent release of Druid?

Will not affect the release of Druid. Druid's Helm Chart is released 
separately. FYI, https://github.com/apache/superset/releases

3. How is it being tested?

It can be verified and tested automatically through Github Action. FYI, 
https://github.com/apache/superset/blob/master/.github/workflows/superset-helm-lint.yml

4. Why is it best to host the helm chart in the druid repo?

Because Helm3 no longer maintains the Helm Chart of Apache-related projects, 
the official also recommends maintaining it in their respective projects. Many 
projects have already done so. The maintenance in the main Druid warehouse can 
be seen by more people and help more people quickly build the Druid environment 
on K8S.

Hope these answers can answer some of your doubts. Thanks again.

Regards,
Benedict Jin
