Thanks for the details. Could you please make sure that checks pre-commit checks are passing?

I'm not sure if this change is needed. There's an existing envFrom field that can add content of a configmap as environment variables

Yes, but then I have to manage a separate configmap just for a small env variable change, makes bootstrapping on new clusters needlessly more difficult
