    Description

      In KIP-740 we had to go through a deprecation cycle in order to change the constructor from the original one which accepted the taskId parameter as a string, to the new one which takes a TaskId object directly. We had considered just changing the signature directly without deprecation as this was never intended to be instantiated by users, rather it just acts as a pass-through metadata class. Sort of by definition if there is no reason to ever instantiate it, this seems to indicate it may be better suited as a public interface with the implementation and constructor as internal APIs.
