Nope. I meant departments. The T10 programs handle CS admissions at the College (Engineering) and Department level.
When you apply for a BS EECS at Cal or BSCS at CMU, it is the CS department (or School of Computer Science) that handles the entire application review process.
Only more traditional LACs (the kinds modeled after Harvard College or Dartmouth College) put all applicants in the same bucket.
But now I see that their reply could also mean that the people are highschoolers at the time they are applying. I understood it as acceptance to high school itself.
Stanford at least doesn't for undergrads. Admissions is handled at the university level and you're encouraged not to even declare a major (CS included) until after your freshman year when you've had a chance to explore options for a major.
Stanford is a more traditional LAC though, so falls under your last paragraph.
