Yes, that is the expected.  It is possible to set the output file to stdout
with "-O -" in which case you do not want to see output of wget itself and
the file content mangled together.

I think it is a convention that debug, informational, error, verbose output
of unix programs be written to stderr.  However, the choice of redirecting
stderr to whatever file descriptor users prefer is always available.
