Yeah, I'm mostly just not sure I want to put a full programming language interpreter in my application, especially Python which is not designed to be embeddable. Moreover, I would really want something that is typed, like TypeScript, but libraries for embedded TypeScript interpreters are even more rare :/.
I figure we'd leave it to the build/deploy/CI/development whatever system. I also don't want to extend or embed my application with a full-blown runtime if I don't have to.
"source" config --> convert to JSON config "on the fly" --> app that expects JSON
edit: I worked on a C++ team that used `std::system` to invoke the system python interpreter when loading a config file. My teammates weren't morons, either, it's just the simplest thing that worked and they knew that the config script and the surrounding file system were secure.
