Basically, high school students who are CSU eligible will get automatically applied to CSU. Most CSU campuses are not impacted, and most majors at non-impacted campuses are not impacted, so baseline CSU eligibility (a-g courses completed with 2.5 recalculated GPA for California residents) means admission.
However, the implementation detail is how to handle students who want impacted campuses or majors. Because admission thresholds are determined competitively, it would not be desirable to automatically apply all CSU eligible students to them, since many have no interest in impacted campuses or majors.
