> I don't expect [the 5% of students who end up going into research] would have called the program particularly optimized either

This. I went to the University of Iowa in the aughts. My experience was that because they didn't cover a lot of the same material in this MIT Missing Semester 2026 list, a lot of the classes went poorly. They had trouble moving students through the material on the syllabus because most students would trip over these kinds of computing basics that are necessary to experiment with the DS+A theory via actual programming. And the department neither added a prereq that covers these basics or nor incorporated them into other courses's syllabi. Instead, they kept trying what wasn't working: having a huge gap between the nominal material and what the average student actually got (but somehow kept going on to the next course). I don't think it did any service to anyone. They could have taken time to actually help most students understand the basics, they could have actually proceeded at a quicker pace through the theoretical material more for the students who actually did understand the basics, they could have ensured their degree actually was a mark of quality in the job market, etc.

It's nice that someone at MIT is recognizing this and putting together this material. The name and about page suggest though it's not something the department has long recognized and uncontroversially integrated into the program (perhaps as an intro class you can test out of), which is still weird.
