I think that is a change of behavior that organizations may get burned on. Right now there is no delete data feature. If an operations teams upgrades to 0.8.2 and someone decides to delete a topic then there will be data loss. The organization may not have wanted that to happen. I would argue to not have a way to "by default" delete data. There is something actionable about consciously turning on a feature that allows anyone with access to kafka-topics (or zookeeper for that matter) to delete Kafka data. If folks want that feature then flip the switch prior to upgrade or after and rolling restart and have at it. By not setting it as default they will know they have to turn it on and figure out what they need to-do from a security perspective (until Kafka gives them that) to protect their data (through network or other type of measures).
