Why common-update-item-referrer-by-path needs a policy

This tool modifies reference data and link relationships across potentially many items in a CMS, which is a reversible write operation. It affects a wide blast radius (all items referencing the target), making it high-severity, but does not irreversibly delete data (Destructive), execute arbitrary code (Execute), or move money (Financial).

From the tool's definition 'Updates all references to the specified item' and 'removes links to the item' indicate modification of data structure and link relationships across multiple items in the Sitecore content management system.

      "limits": [
        {
          "counter": "common-update-item-referrer-by-path_rate",
          "window": "minute",
          "max": 30,

        }
      ]
