In my experience, the only thing that cares about the primary nameserver
field in the SOA is DNS updates.  If not accepting updates, I've been
inclined to do things like:

; ORIGIN is domain.example.
@         SOA    loopback.domain.example. hostmaster.domain.example ...
          ...
loopback  A      127.0.0.1

This deals with the annoying habit of Microsoft clients that attempt to
update the DNS when they come up.  You just wouldn't believe how much
bogus update traffic the registered primary of a TLD gets without that
trick.

There's an unusually warm place in Hell reserved for the Microsoftie that
made that decision to make "update DNS" the default.

Is there anything else that relies on the primary field of the SOA?
