Trying to hot plug or hot unplug a high voltage wire is hazardous whether it is shielded or not. 

Would not having the return wire (ground, B- or whatever you want to call it) part the same cable increase the chances that some mechanical mishap would result in the two sides shorting together, blowing a fuse and discharging the filter capacitors? Whereas a single B+ lead by itself could be severed or unplugged and remain hot, creating a long lasting hazardous situation?
