This is spot on. My brief exposure to Jsonnet made me realize how superior it can be, especially for k8s manifests. Unfortunately the learning curve is steep, to the point that I've held off on attempting to introduce it anywhere new. Recently I discovered kpt (https://kpt.dev/ https://kpt.dev/), which attempts to improve the k8s manifest situation and seems to have a lot of good ideas. Considering how long it's been under development though, it may also never catch on among mainstream k8s users. Grafana recently switched their dashboard DSL to one based on Cue. I haven't yet dug into learning it, but it seems potentially even more powerful than Jsonnet. They also have the advantages of a much smaller audience (relative to k8s manifests) and of putting in the work up front to define the new language and a sample implementation (useful out of the box), not to mention making it a requirement going forward.
