New description:

 (for less verbose output in CLI)

         Valid use case:
         `ffmpeg -hide_banner -nostdin -v warning -i ${in0} -i ${in1}
 -lavfi "ssim; [0][1]psnr" -f null -`

         This currently gives nothing at all... for which cataloged "info".

Comment (by MasterQuestionable):

 What are the potential caveats of doing so?
         Is there significant CLI usage that causes abort on warning
 meanwhile using the named filters?
