JIRA: KAFKA-12916
Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

Currently Kafka supports creation new topics through a CreateTopicsRequest or by auto creation during a topic MetadataRequest (if enabled on the cluster). Kafka supports ACLs for creation but currently the CREATE acl is used to grant access to both types of topic creations. This is problematic because it may be desirable to allow a user to auto create topics but not to be able to submit a create topic request. The difference is that auto creation will use the cluster defaults for the new topic settings but a topic creation request would allow the user to have control to configure all of the different topic settings which may not be what was intended.
