Realistically, a plain helm install without any values rarely if ever gives you the deployment you need, so you have to study the chart anyways.

This is hardly unique to helm.

In 2025 you should probably be using gitops anyways, in which case the git repo is your history.

So what? The guy was asking what is nice about Helm vs Kustomize. Does Kustomize have rollbacks?

Gitops is literally just "hey I have some configs in Git and I run some command based on a checkout", i.e. infrastructure as code in a git repo. Gitops does not track live server metadata and deployment history. I don't get why people over-inflate this idea.
