  /**
   * Rules are grouped by plugin. If you want to override a specific rule inside
   * the recommended set, then it's recommended to spread the new rule on top
   * of the predefined ones.
   *
   * For example: if you want to enable a new plugin in the codebase and their
   * recommended rules (or a new rule that's part of an existing plugin)
   *
   * 1. First you'd setup a configuration object for that plugin:
   *    {
   *      name: 'my-plugin/recommended',
   *      ...myPlugin.configs.recommended,
   *    },
   *
   * 2. Second you'd override the rule you want to deal with, maybe making it a
   *    warning to start:
   *    {
   *      name: 'my-plugin/recommended',
   *      ...myPlugin.configs.recommended,
   *      rules: {
   *        ['a-rule-outside-the-recommended-list']: 'error',
   *
   *        ...myPlugin.configs.recommended.rules,
   *        ['a-recommended-rule']: 'warn',
   *      }
   *    },
   *
   * 3. Finally, once all warnings are fixed, update from 'warning' to 'error',
   *    or remove the override and rely on the recommended rules again.
