If you have an efficient way to grab the disk state from an observer, this will, indeed, make starting a new observer less expensive to the cluster. In practice, this isn't a big deal since the ZK snapshot is bounded by memory size and transferring a few GB across the network isn't all that painful as a one-time cost.
