It is not UDF / filesystem specific stuff. You can use any other
filesystem which you like, for example ext4. And in past some people
really used ext2 on CD-RWs. And on Windows systems before Vista, only
FAT32 was supported in read-write mode on CD-RW. UDF even on CD-RW was
read-only.

So FUSE here really does not help. As we are talking about block
storage, not filesystem storage.
