Well, if /dev/stdin works then it's ok, of course.

No. That's plain data stream writing.
Like with a tape.
For getting an ISO filesystem with a tar file
in it you would have to put an ISO hull around
the data stream in a pipe (hardly possible without
predicting the size) or you would have to put it
on hard disk and let growisofs use its builtin
pipe to mkisofs:
growisofs -Z /dev/hdc my_tar_archive.tgz
Note that there is no '=' after /dev/hdc.
The argument my_tar_archive.tgz goes to
mkisofs which generates an ISO image into
a pipe that gets read by growisofs and
written to media.
Paul Serice's backup system "shunt" comes to
my mind. It produces tar archives and packs
them into an on-the-fly generated ISO system.
(It talks of growisofs as of about year 2004.)

Yes. That is one of the advantages.
It works out of the box if you have rw-access
to /dev/hdc (in general: the block device ruling
Have a nice day :)
