It's not too oversimplified. I have a library chart that's optimized for running a web app. Then each web app uses that library chart. Each chart has reasonable default values that likely won't have to change so you're left only having to change the options that change per app. That's values like number of replicas, which Docker image to pull, resource limits and a couple of timeout related values (probes, database migration, etc.). Before you know it, you're at 15ish lines of really straight forward configuration like `replicaCount: 3`.
