LGTM. Thanks @jmmc-tools

Do other components such as master or API-server also need this feature?

[jmmc-tools]

It's not mandatory to add more components for this feature request.

The current scope focuses on the specific worker component, and extending it to master or API-server would be a separate consideration that could be evaluated in future iterations if needed.

[Gallardot]

LGTM. However, we need to update the values.yaml file at the same time so that users know about this feature.
