Snap shackles have multiple potential failure points; the hinge pin, the metal castings, the release pin, the swivel pin, the bail, etc.
If the snapshackle is on a wire, there's the swage eye with a couple failure points. A line with a bowline has only one (philosophically speaking). One could tie a rolling hitch around the wire above the swage eye and eliminate the snap shackle. You'd have to use a small size high tech line. Not sure I'd like that practice. I think I'd rather see if I could get a regular shackle into the swage eye or the bail of the snap shackle before I hung from the snap shackle itself. BTW, I always tie off to the masthead once hoisted. Dennis C.
