Optional query parameter that controls whether the response should include referencers metadata.
When set to true, the response will contain an additional _referencers JSON node with information about entities that reference this entity (e.g. referrer template, attribute, count, etc.).
If this query parameter is not provided, a default behavior will be applied. The default value is configurable and may differ between environments.
Note: Enabling referencers information may impact performance, as additional data needs to be resolved and returned.
