Of course they don't follow a specification. An example from a freshly generated angular project: ```json /* To learn more about Typescript configuration file: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html. */ /* To learn more about Angular compiler options: https://angular.dev/reference/configs/angular-compiler-options. */ { "extends": "./tsconfig.json", "compilerOptions": { "outDir": "./out-tsc/app", "types": [] }, "files": [ "src/main.ts" ], "include": [ "src/**/*.d.ts" ] } ``` Not sure which side is wrong here. The short sighted specification or the specification ignoring usage. -- This is an automated message from the Apache Git Service.
