Well, I don't know the original argument for doing it this way, but
I've got two:

1. the command is meant to be a filter, stdin to stdout, anything on
stderr almost certainly indicates a problem.

2. sadly there are still filters that return zero if they fail and
non-zero if they succeed (especially user written ones :), which means
that you can't just test the return value.
