I've been observing the zookeeper mailing list for 3.4.x and haven't found it to be particularly stable. There are still serious issues being reported like leader election failures, ephemeral node deletion. I'm sure they are being fixed and there are many early adopters. But my guess is that we should probably release 0.8 on a proven stable version and look into 3.4.x for Kafka 0.8.1.
