Neither Windows nor OS X have such a requirement, and yet they co-exist and can boot their siblings of various versions just fine. Now, ostensibly os-prober can read content without them being mounted, so it can find /etc/fstab, and various other things it's looking for, to figure out what systems are installed and how to put them together so it can create a grub.cfg entry for them. Because of the litany of completely non-standard layouts possible by linux alone, this can be a problem, not least of which is if root is encrypted.
