Pulsar is a very interesting architectural case study. The cost of the greater clarity and flexibility is the greater management burden. The server-side functions are nice (and remind of JEE MBeans) but the direct challenge to Kafka is the decoupling of storage from servers via Bookkeeper (which adds the lower layer cluster management burden) which addresses the rebalancing headaches with Kafka type of solution (where the server and storage are unified).
