I think with the modified virus you don't just have the intentional vs accidental release dichotomy, but two additional items: (1) was the intent of the research plainly scientific or oriented towards weaponization, and (2) whether changes in virus traits are due to "genetic engineering" or not. Because there are ways in which both of these can have answers less satisfying than a law of nature, they add another degree or yelling past each other to at least the range of 3 to 4.
