Unless the classes are deliberately hard or mistaught, the concept is absurd. To keep people in chemistry, remove organic chemistry (or physical chemistry for the math phobic). To keep people in physics, weed out non-survey relativity. Basic knowledge of the field is required to provide a basis for choice and further training. If you mean STEM = software developers, design the training to fit the desire. If CS is a theory-heavy degree, create the engineering alternative as they did with chemistry.
