Is there a reason you wouldn't want to just push the data into something
built for cheap, long-term storage (like glacier, S3, or HDFS) and perhaps
"replay" from that instead of from the kafka brokers?  I can't speak for
Jay, Jun or Neha, but I believe the expected usage of Kafka is essentially
as a buffering mechanism to take the edge off the natural ebb-n-flow of
unpredictable internet traffic.  The highly available, long-term storage of
data is probably not at the top of their list of use cases when making
design decisions.
