I've done running changes on Tiger Moths (pax seat at front) and anybody who's been to Duxford on a day when the Tiger / Rapide guys are flying must have seen them happen. The geography of the a/c with the longish nose, steep wing lateral gradient as you are standing on it (so you would fall backwards), the propwash trying to blow you off the wing, and the flying wires in the way, combined with the pilot having his hand on the mag switches and an additional set of mag switches within reach, make it tolerably safe IMO.
I cringe when I see people handling propellers casually, putting arms and necks through the discs on walkarounds, pull aircraft by the blades, curl fingers around the trailing edge when hand-swinging or sucking in, stand or walk too close to props and tail rotors
I agree apart from one thing - pulling a/c by the prop. I have even done this on an a/c that was known to have a live mag. Is this actually very unsafe and am I an idiot? Viewpoints appreciated
