I'm confused what you expected this command to do. You wanted to
"destroy" (by overwriting with random data) a pipe to wc? What
would that even look like?
The basic premise of shred is that it determines the size of the file,
then writes data over it, rewinds it, and repeats this a few times.
A pipe to a process has no size, and can't be rewound.
Declaring a pipe to be an "invalid file type" for shredding sounds
pretty reasonable to me.
