Even then, if you write directly to /dev/sdD0/data, you'll need to fixate (close) the disc. I'm not sure what there is to fear about iso 9660 format. It doesn't encrypt your data and files tend to be written contiguously (I'm not sure if that's required by the format or just a good idea to make reading faster), so digging the data out by hand shouldn't be difficult if suddenly all the world's 9660-reading programs stopped working. Note that using cdfs doesn't imply use of 9660 format, and using cdfs would take care of fixating the disc at least.
