1 Not that I've found, on anybody over the age of five.
2 True, but they do actually say 'Open' and 'Closed'. That obviously is meaningless to lawyers' clients.
3 Simply riding into big potholes could also cause catastrophic accidents.
4 Only if you point QRs in such a manner to allow this AND ride 'dangerously close' to objects.
5 Not if the front disc brake is mounted on the RH fork blade or in front of the fork blade. This is a fork manufacturer's problem regarding brake location, not a QR problem.
6 It is amazing how many things on a bike or virtually anything else can be tightened when not fully seated (seatpost, handlebar stem, etc).
