 While generally developers should not rely on manual task escalation handling, this API also does introduce a manual way to escalate a task's priority. Primarily this should be used in combination with a task escalation handler to _propagate_ an escalation to an _unstructured task_ which otherwise would miss reacting to the escalation.
