I agree.  Since any multiple-output-file case can't usefully use stdout,
I think we should combine the switches and just have one switch that
says both that you want separated output and what the target filename
is.  Thus something like
--pre-schema-file = foo--data-file = bar--post-schema-file = baz

where specifying any of these suppresses the "normal" output to stdout.
So, if you give just a subset of them, you get just subset output.

With this design, --schema-only, --data-only, and --file are obsolete,
and we should probably throw an error if any of them are used in
combination with these switches.
