Not necessarily. The daemon might use a third-party library
which writes diagnostic messages to stderr (something like
Oracle's libs). Or even worse, the user might be running the
application on FreeBSD where malloc(3) writes messages to
stderr, if configured to do so. There are probably more
cases where this can happen which the app's author cannot
influence. Supplying module authors with a function which
addresses this issue makes sense from that perspective.
