Yes, of course there are risky systems in there, and calling attention to one of them is fine. What I object to is framing it as a "safe/not safe" issue - as if without the tests the author proposed it were "not safe" and with them, by implication, it would become "safe". That's not like replacing old tires on your car with new tires - there are a lot of things that can go wrong, and many of them are "unsafe", and it's always a complex equation which can not be (at least at current level of technology) solved with doing more tests or anything else to make it "safe". The "safe" framing is the one I object to.
