Galaxy brain: if your config is programmable, it can read whatever terrible configuration format you want. That means my settings.py (yes, I'm forced to use Django) is configured via environment, which is populated by k8s from - gasp - JSON files. That means that if I wanted to configure Vagrant with JSON, there is no force in the universe that could stop me. If the config file is actually a normal program, then it can do normal program things, then any benefit from using JSON instead is nullified by the fact that you can still use JSON. In turn, if your tools primary configuration is via a more limited settings, you're stuck with it. Not even "generators in other languages" allow comparable runtime flexibility.
