Well, it looks we've re-discovered what inspired this thread in the first place!
That is, the horrors we correct would not have been allowed in 1940 - let alone now! I just don't see, for example, the dangers of Edison base fuses and K&T wiring ... at least, not as compared to OVERfusing and duct-taped flying splices. Plus I don't feel particularly at risk having my bathroom receptacle as part of a general lighting circuit (receptacle is part of the fixture).
