NFSv4: mount -t nsf4 not the same as mount_newnfs?

My understanding (from having used NFS and ZFS, haven't looked at the code)
is that:

The sharenfs property for a ZFS dataset gets written out to
/etc/zfs/exports, which gets appended to the mountd command-line by default.
 Thus, you can use /etc/exports or sharenfs property, whichever is easier.

# zfs get sharenfs storage/backup
NAME            PROPERTY  VALUE                       SOURCE
storage/backup  sharenfs  -maproot=root 192.168.0.12  local

# cat /etc/exports

# cat /etc/zfs/exports
# !!! DO NOT EDIT THIS FILE MANUALLY !!!

/storage/backup -maproot=root 192.168.0.12

# pgrep -lf exports
1381 /usr/sbin/mountd -r -p 32000 /etc/exports /etc/zfs/exports
