Could be, but that's a lot more work to do when reading applications. Inferring these facts from a heterogeneous and unstructured data source, like hundreds or thousands of bios, requires a lot of effort that is better spent elsewhere. Setting these up as simple red flags, through a series of boxes to check or not check, solves the problem more efficiently. Right off the bat, you can sort all applications by any of the criteria in these boxes. You can do that before even starting to read them. If you're inferring from bios, on the other hand, you have to read every bio before you can sort.
