No. Mostly it is unused, but the MNAME field of the SOA record *has*
to point at the zone's master server if dynamic updates are in use.
The SOA's MNAME is the only way of reliably identifying the zone's
master name server. And hosts doing dynamic updates need to know where
the zone's master server is.
