Helm works at text level. This approach could have worked with YAML, JSON, XML or any other text format. You can template C++ code with Helm if you really want.

Helm works at text level. This approach could have worked with YAML, JSON, XML or any other text format. You can template C++ code with Helm if you really want. It's just golang templates below. And that makes it wrong. YAML is structured format and proper templating should work with JSON-like data structures, not with text. Kustomize is better example.
