Seems like the NACAC list may not be exhaustive, if some colleges do not tell NACAC or NACAC does not look at them.
For example, Application Dates & Deadlines | CSU says that CSU Maritime Academy is still open for frosh applications for some majors, and a larger number of CSUs is still open for upper division transfer applications for some majors. But they are not on the NACAC list as of now.
