I like my cynicism touched with realism.

No that is a smart question.

MNAME is used to identify the "primary" DNS server when sending
dynamic DNS updates.

If you don't use dynamic DNS, MNAME is not used. 

Other people, and their resolvers, don't know and don't care
which is your master, and which is your slave*. 

Indeed the DNS protocol doesn't mandate that you need a master
and slave implementation, both W2K DNS and TinyDNS mainly use
"multimaster" schemes, and replicate data between authoritative
server by means other than AXFR or IXFR, and they both work
(well one works better than the other IMHO, but that is another
debate).

* except as Cricket points out for the period when your slaves
have older data than your master, then other people might care
briefly.
