I'm stunned that people are advocating anything less. Do it right. Ride safe.
Can you explain? In what situation would having less axle protrusion be dangerous?
The only situation i can think of is if your QR was not only untightened, but actually fell completely out. Then the wheel would slip out. However, even with the axle protrusions, it would probably still come out as soon as you hit a bump or something.
It sounds like a far fetched situation anyway.
