OK.. it's a stupid way to do it, add completely possible unnecessary failure modes and they shouldn't repeat it. But is it actually that dangerous. The edges aren't that sharp, the load isn't too bad and bolts are strong.
Completely Stupid: YES, Needs education: YES, inevitable immediate death: NO.
Personally if they were doing something as daft as that, I'd be more worried about -- what on earth else are they doing?
