What about the lack of a mature language server for code completion and at-your-fingertips documentation? What about the lack of mature tooling for static analysis, linting, code formatting, etc?

What about the poor support for defaults and partial overrides on object-type (read: namespaced without redundant_underscore_thing_*) configuration directives?

What about the very limited module capabilities?

What about the limited set of deterministic functions available (e.g. you get base64, yaml, csv, and otherwise GLHF)?
