Review Comment:
Why did you move this method? It seems Matthias moved it on purpose and you
are reverting his change here?

Review Comment:
I'm not sure I'm mega happy with this log message, as every user trying a
basic example of Kafka Streams will be confronted with it. But I see it was
part of the KIP and this proposal was accepted. I added a little note to the
VOTE thread, to point out that this log was part of the KIP - I had missed it.
But I'm okay with going forward with the KIP as accepted if nobody shares my
concerns.
