No ... not by default. If a JSON file only contains public site data and reinforces the page content, letting it stay visible can help search engines and AI systems understand the site.
The decision should be based on sensitivity, not habit. If the file exposes admin details, secrets, or internal-only logic, keep it private.
If the file simply mirrors public content such as glossary terms, directory listings, library sections, or AI endpoint summaries, leaving it visible can improve inspectability and machine readability.
This site is scaffolded with that public-by-default approach in mind.
