I thought I saw mention somewhere of changing the default of auto.create.topics.enable to false.
I searched, but couldn't find anything in JIRA... am I imagining things? Now that there's API support for creating topics, the version bump to 0.11.0 seems like a good time to re-evaluate whether this default should be flipped to false. I'm happy to create a KIP if needed, just didn't want to duplicate effort.
