Yes, but there is a nice simplicity in saying filesystems that support 64bit device numbers get the expanded space, and filesystems that cannot are limited to 16bits. Most modern systems would have an updated set of filesystems. All pre-existing filesystems have only 16bit device numbers. All new mknod64() calls will only work on filesystems that can store 64bits.
