The School of Engineering, in this case, is trying to teach something more than just domain knowledge about engineering disciplines. The goal is to take those "18 year-old polyglots" and turn them into world-class problem solvers.
You see this is every elite educational program. Mathematics at Chicago. Computer Science at Carnegie Mellon. Engineering at MIT. Their programs have a difference in kind, and are very intentionally not built for "the average college student".
It's good that there's an alternative path within the same institution for those students who need to focus their efforts on baseline competence. But it's also good that strong programs expect more out of their students.
