It doesn't do round-robin, or any of the other things that normal
authoritative-only servers should do, but which are not strictly
required for use on serving TLD data.

Right. It's designed for root servers and TLD servers. It's not
designed for general-purpose authoritative-only purposes.
Even for root and TLD servers, there are internal issues with the
code that prevent it being used for some TLD providers, primarily
having to do with the day the program wants to load all data in
memory (and the particular type of uncompressed jump table that is
built), etc....
That is unless you folks have changed a lot more since I last
looked at the program than I had thought.
