> Currently Producer will always send the record with the highest magic format version that is supported by both the produce and broker library regardless of log.message.format.version config in the broker.
> This causes unnecessary message downconvert overhead if log.message.format.version has not been upgraded and producer/broker library has been upgraded. It is preferred for produce to produce message with format version no higher than the log.message.format.version configured in the broker.
