Prior to that, it was simply ignored; the problem here is that if someone has this in their fstab for the root fs, now the box fails to boot properly, because remount of root with the new options will fail, and the box proceeds with a readonly root. I think it is a little nicer behavior to accept the option, but warn that it's being ignored, rather than failing the mount, but that might be a subjective matter...
