As someone that has both Kafka and Redis in use without issue, for years, (and is about to replace a lot of misused Redis instances with Kafka) I really fail to follow your points.

So, a Zookeeper cluster can't survive accidentally injecting just the right malicious data that will make it keel over. I'm sorry, how do you accidentally achieve that? Do you also accidentally configure your Redis Sentinel to replicate from /dev/null?

As a matter of fact, this announcement comes at a very inopportune time for me. antirez had the epiphany of reading on IRC about replicated logs instead of looking at the opening paragraphs of the Kafka documentation, and all the Redis evangelists at my job will now try to shoe-horn the wrong usecase back into Redis because Redis!1cos(0)!. Sigh.
