bq. Do we currently have a JIRA open for this? I've lost track.

[~apurtell] There are probably a few.  Here is one HBASE-10295

> Our [design invariants state that ZooKeeper data is safe to delete|http://hbase.apache.org/book/developing.html#design.invariants.zk.data]. However, [replication only stores its data in zookeeper|http://hbase.apache.org/replication.html#Replication_Zookeeper_State]. 
> This can lead to operators accidentally disabling their replication set up while attempting to recover from an unrelated issue by clearing the zk state.
> We should update the [operational concerns section on replication|http://hbase.apache.org/book/cluster_replication.html] to call out that the /hbase/replication tree should not be deleted. We should probably also add a warning to the set up steps.
