Having an additional option to refer to a certain file descriptor
sounds worthwhile and tempting.  OTOH, you can already refer to
/dev/stderr as a file name for the 2nd file descriptor already
on many/most systems:

  echo big long complicated error message goes here | tee /dev/stderr

Does this work for you?
