There are so many that I can't even begin to speculate which ones might be the case here... maybe they lost them, maybe they have Top Secret commercial data (like BRL-CAD's other test suite, which contains military data), maybe they don't want anyone to do major refactors without putting in the effort to make new tests..... Like I said, lots of possible reasons. I haven't asked them.
