Piotr Dabrowski asked this recently, and my response then was:

"Using the --quiet option for this seems a little awkward.
One reason we added the --raw option, was for this single input case.
I.e. please consider using something like this example:"

   cksum --raw -a md5 | basenc --base16

Now the BSDs implementing -q for this does change things a bit,
as we'd be adding compat, albeit without adding functionality.
So given there are two separate suggestions for this and
we're increasing compat, I'm 55:45 for adding this now.

Note FreeBSD at least will output checksums without file name
for all specified files, though that would be an unusual use case.
