+      Virtual Services optionally accept a wildcard as an alternative
+      to precise matching. In some cases, this may be too permissive as it
+      would direct unintended traffic to the given resource. This
+      policy enforces that any Virtual Service host does not contain a wildcard
+      character and allows for more governance when a single mesh deployment
+      model is used.
