I have not. However, looking at it now, it falls into the same problems all template generators have. Those are things solved by using general purpose languages generate rather than templating manifests. KCL is in the middle ground. The Ruby mixins I can use for manifest generation can has an equivalence with KCL's union. I can see Timoni's appeal as it looks like an improvement over Helm and integrates building artifacts.
