Review Comment:
Yes, but the problem is, that `serializeBaseKey` is inherited by public
classes `TimeWindowedSerializer` and `SessionWindowedSerializer`, and thus this
method is (unintentionally) part of the public API, even if this interface
itself is not public :(
That's why I filed KAFKA-20313...
