If I understand you correctly, libraries should return the errno (because
errors may mean strings also), and not try writing anything to stderr. The
application should do the job of writing to stderr.

Is that just your opinion OR is it accepted programming practice OR is it
documented somewhere ?..

The reason I ask this is because I know of atleast one library (pthread)
that writes stuff to stderr (ofcourse, only under some circumstances)
