> In the initial implementation of KIP-924 in version 3.8, we converted from the new TaskAssignor's output type (TaskAssignment) into the old ClientState-based assignment representation. This allowed us to plug in a custom assignor without converting all the internal mechanisms that occur after the KafkaStreams client level assignment and process it into a consumer level assignment.
> However we ultimately want to get rid of ClientState altogether, so we need to invert this logic so that we instead convert the ClientState into a TaskAssignment and then use the TaskAssignment to process the assigned tasks into consumer Assignments
