So, I am guessing one _always_ extracts one of the outputs and then apply a
filter. Does it make sense to apply the same filter to both outputs?

I am trying to figure out whether the output of this reader should
multi-block. It sounds like it should not. It sounds like the two outputs
have different purposes and should remain separate.

Currently, paraview only handles multi-block datasets. There was code in
paraview 2.4 and previous that treated multiple outputs as multi-block. This
was a placeholder we implemented until we had proper multi-block support.
Now that the multi-block support is mature, I yanked that functionality. The
side effect of this yanking is that it is no longer possible to separate the
outputs of readers like this. However, I believe that paraview should start
treating multiple output differently. For example, it should show both
outputs as different ports you can attach filters to. Or when the user
applies a filter to this reader, it should bring a dialog asking which
output they want to attach the filter  to. Supporting this would require
changing both the server manager and the GUI code but I believe it is right
thing to do. Any thoughts?
