I don't understand why I would use this over Helm? I am even further confused when I go to the docs and it has guides for creating a kpt package from a helm chart: https://googlecontainertools.github.io/kpt/guides/ecosystem/

If you are going to introduce a new tool into an already crowded ecosystem the least you can do is describe why anyone should use it.

One key distinction is that this is not yet another templating DSL like Jinja, or Go templates that present an anti-pattern for non-trivial deployments. As an example, take a look at the Grafana Helm chart:

https://github.com/bitnami/charts/blob/master/bitnami/grafan...

It's more curly brackets than YAML :)

Instead, kpt's key design philosophy is to keep configuration as data. This makes it easier to develop tooling that operate on configs.
