Yea, anything that allows you to think in a higher-level than raw kube objects will save you a lot of time and heartache. For instance, if your application needs a redis cluster in helm you have to mess with subcharts/other headaches. In jsonnet it becomes `redis = import "redis"; redis.Cluster("my-app-name") { nodes: 10 }` or something similar.

DRY configs make me very happy.
