> Right now Stream could not handle the case when the brokers are downgraded, thus potentially could violate EOS requirement. We could add an (internal) config to either consumer or producer to actually crash on unsupported version when the broker connecting to is on an older version unexpectedly, to prevent this case from causing correctness concern.
