Hi Maxim, I had a quick look, it seems like that was added to the Apache Kafka documentation only in version 1.1.1, which didn't get a doc update being only a patch version, so the relevant sentence is only in the docs for 2.0 [1]. Additionally, the passage was only added to the docs of the topic level setting, not for the broker setting, in case you checked there, that is why you didn't see it :)
I've created a pull request to add this to the broker level setting as well. Hope that helps?
