Yeah, I think the difference is that I was

a) Learning K8s and Helm Concepts (both different things)

b) Reading/Debugging K8s and Helm YAML (both different things)

c) Ending up at Helm Chart Configs (another config)

d) Figuring out how to set all this to helm me deploy the solution I needed and customize it acc to my needs

...all within the span of a few weeks.

So by the time I got to some GitHub repos which were using Jsonnet, I was basically done. I'm sure it has its uses and given enough time and experience, I can see how to utilize it more effectively.
