Unfortunately it doesn't really because of the extension issue I mentioned. Certain file names (like `tsconfig.json`) are whitelisted to have JSONC support, but any random file `foo.json` will be treated as JSON and give you annoying lints if you put comments and trailing commas in.
- it has good editor support (VsCode) - has comments support - Support jsonschema
Only thing missing is trailing commas, but i would rather live without trailing commas than tooling support
