+ * This function handles store status events, particularly in cases where there
+ * is insufficient storage capacity for new records.
+ * It attempts to resolve overflow issues by deleting the oldest bond and
+ * proceeds with the persist operation.
+ *
+ * @note This behavior may not be suitable for production use as it may lead to
+ * removal of important bonds by less relevant peers. It is more useful for
+ * demonstration purposes and sample applications.
+ *
+ * @note Retained for backward compatibility.  It follows the eviction policy
+ * selected at build time, so it removes the least recently used bond instead
+ * of the oldest one when the least-recently-used policy is enabled.  New
+ * applications should use ble_store_util_status_overflow().
+ *
+ * @param event                 A pointer to the store status event.
