Review Comment:
I see, agree that makes total sense in the close (kind of "terminal" state
for the consumer), but for the unsubscribe would probably make sense to put a
little more effort in making sure that the member "properly" leaves the group
(sending last HB). We would need to think a bit more about the implications so
I filed https://issues.apache.org/jira/browse/KAFKA-15954 to review that as a
follow-up.
