I guess it's like HTML if it tried to also adopt it's own scripting language. Whereas JS interacts with the HTML DOM. Sure, it has quirks, but essentially modified a config.

I've never found a nice way writing YAML with variables and configurability.
Trying to use yaml to natively describe how a yaml config should be produced is broken. It diverges from the underlying schema, and (because it's .yaml) isn't distinguishable from any other yaml.
Things like helm treat yaml as a template. And I don't think language servers & tooling are up to scratch yet (happy to be corrected). So basic yaml formatters shit the bed.

Yaml is a computer readable config file that tries to be human readable, and fails at being actually useful.

Why projects try and make it useful, I will never understand.

I honestly think generating yaml from something like python would be a million times easier.
But then tools like ansible adopt yaml to essentially be a scripting language. As opposed to creating an actually decent solution that uses both python (to generate) and yaml (to apply).
Or whatever language.
