I'd argue the other way around, that mount should display what's
configured even if some options do nothing in combination. 

noatime and async also do nothing in combination with ro, but mount
will still display them:

# mount -o ro,noatime,async /dev/md31 /mnt/t

# mount | grep md31
/dev/md31 on /mnt/t (ufs, asynchronous, local, noatime, read-only)
