I think you misunderstand what dd takes on stdin. From "info dd":

"`dd' copies a file (from standard input to standard output, by default) with
a changeable I/O block size, while optionally performing conversions on it."

It does not take filenames on stdin.

Um, you've provided one example: tar. Where are the others?

Unless someone contributes a patch, I doubt the filenames-on-stdin feature
will get added to coreutils (which incorporates fileutils). I expect Jim
Meyering (the maintainer) is pretty busy already with existing coreutils work.
