With all the code syntax highlighting support as a feature, I feel it will become tempting to put code in configuration files (which some of their examples show). That just feels wrong. Code should go in code files/modules/libraries, not mixed with configuration files. If your configuration starts to become code, maybe you need to rethink your software architecture. Or perhaps KSON proves that principle to be too rigid and inferior, and leads to more intelligible, manageable software. I guess we'll have to see.

We agree that there are lots of situations where code ideally does not belong in configuration files, and perhaps if it gets out of hand you need to rethink your software architecture.

However, reality shows that embedded code in configs is already widespread - think SQL queries in dbt, bash scripts in CI/CD configs, or regex patterns in routing rules. These aren't going away. KSON's embed blocks acknowledge this reality while making it safer and more maintainable through proper syntax highlighting, validation, and clear boundaries. We're not encouraging bad practices, we're providing better tooling for existing patterns.
