Hi, apologies for late response, I don't check this account that often.

I disagree that the South Campus shouldn't be included, plenty of other universities' "separate" campus have been included in the OpenStreetMap Relation (see: UC Berkeley's Kerr Campus, UT Austin's Pickle Campus, Syracuse University's South Campus, or the University of Buffalo's South Campus)

South Campus aside, why aren't SJSU's other sites included? Per SJSU's website, the Hammer Theater, Alquist Building, Campus Village 6, North Parking Garage, Child Development Center, Community Garden, and International House are all considered to be a part of the "main campus". I don't see why they should not be included. Again, many universities' OpenStreetMap Relations include facilities even if those facilities are a block or two away from a contiguous "main campus" (see: Harvard, Princeton, the University of Virginia, UCLA, or the University of Michigan)
