YAML and Configuration Files
My stance is that YAML is a good format for configuration management and generation -- it's wonderful at filling gaps as your deployment model increases in complexity to provide a mechanism to "render" your configuration -- much like Skylark [1] does (derived from Google's internal GCL).
YAML ends up being a powerfully declarative model [2] for the state of a data structure, rather than a straight representation, ironically often enough being used in turn for an imperative model like in Ansible [3]. Definitely friendlier than JSON. But personally, I really like YAML because it lets me compose using a traits/mixins-like model using & and , which allows for verbose, structured configuration inputs but concise configuration files.
docker-compose YAML files extension fields [4], imo, are a great example of this type of model in action. When you leave this much pre-deserialization flexibility in your configuration representation, it makes building cool stuff like docker-compose ECS support x-aws- extension keys [5] and other plugin system-type capabilities much more straightforward than, for example, adding a new language feature to HCL.
