From my personal experience the most common use of master only NS
systems is for complex view based setups that need to avoid the xfr
problems of views to slaves.
Of course there are security issues. These are usually dealt with by
having at least one (hopefully pristine) hidden master.

Google for unxsBind (Bind9+ multi name server set and multiple end user
DNS manager), it does use local per master rndc commands but not rsync,
instead it uses a different SQL based job queue mechanism for
replication of master data that scales very well.
