I too wonder the same...

The real-world provides us many examples of such big -> little, or smart -> not-as smart workflows. For instance, we don't typically ask juniors or mid-level SDEs to design solutions to exceedingly challenging problems for a reason. However there are _some_ areas that those with less experience can tackle that is relatively risk-free if their work is reviewed by a more experienced engineer, which leads me to a conclude that it's task dependent.
