It's sometimes useful to have a disk-drive-like device that can accept anything (the fabled write-only media!), mostly for development. Also, gzero can be configured to "be made of" not only zeroes (\0) but any other byte value, so it can be useful if you need "something like /dev/zero" but not with actual ASCII 0 bytes.
