The friction is still too much IMO. While I love the configuration languages, I still find myself writing YAML because it's much simpler. The tooling support is getting there but I don't understand why these tools introduce their own syntax and type system rather than being a superset of YML or JSON and using JSON Schema as the type system. I was an evangelist for Jsonnet but somehow it didn't get enough traction over time. I blame the lack of type support and integrations with the IDEs such as VSCode. I regularly check the VSCode & Intellij support for CUE as well but the support is still at the level of syntax highlighing, not more than that, which is sad. Nowadays, I use VSCode with YML extensions (anchor, etc.) and use JSON Schema to validate the YML in the IDE with its language server. It's far from perfect but easy to iterate and portable.
