I can say that I've personally had a Loctited suicide hub fail on me and come unthreaded right in front of an intersection. Luckily it was a fresh red so I was able to get through before there was any crossing traffic - looking back I can't believe I was crazy enough to run that setup without a brake, but I was a noob and didn't really understand what was going on. Just do it with a brake and it it'll be more of an inconvenience than a safety hazard if it wants to come unthreaded on you.
