Sorry, I notice now this:

Why would mount instead of nmount be more useful?

/usr/src/sbin/mount/mount.c notes that

         /* XXX: We need to get away from implementing external mount
          *      programs for every filesystem, and move towards having
          *      each filesystem properly implement the nmount() system 
call.
          */

It might be that mount_nullfs only works at the moment with the 
nmount-based implementation, in which case you would need to work around 
this.
