No, you misunderstand.

Redirecting stderr (or stdout) merely sends the progress info to that 
destination. Piping input on stdin will turn it off, so there's no progress 
info to redirect.

Writing progress to stderr is the correct thing to do, because it's transient 
info that isn't meant to be saved. Checking whether stdout is redirected or 
not is fine, but writing progress info to stdout is not.
