I agree, and I just want to highlight what you said about generating a config file. It's extremely useful to constrain the config itself to something that can go in a json file or whatever. It makes the config simpler, easier to consume, and easier to document. But when it comes to _writing_ the config file, we should all use a programming language, and preferably a statically typed language that can check for errors and give nice auto complete and inline documentation.

I think aws cdk is a good example of this. Writing plain cloudformation is a pain. CDK solves this not by extending cloudformation with programming capabilities, but by generating the cloudformation for you. And the cloudformation is still a fairly simple, stable input for aws to consume.
