Regarding the pig-tailing of the neutral only, I've seen the hot conductor also burn up. A termination, that is subjected to a continuous heavy load is subject to heating and becoming loose. If all that's being used in a termination is a tiny bent piece of brass, holding the connection, any heating will cause it to lose it's tension.

Yes, that's just what I meant, for two or three pole multi wire branch circuits. I wonder if they need three pole breakers for three phase multi wire circuits now? This will be really annoying in some circumstances - say in an office if someone uses a plug in space heater and trips the three pole breaker to three or six desks, killing power to all the computers!
I don't support the use of "back stab" connections at all.. when I have wired houses I always use the screw terminals, even if it will take a little bit of extra time. I can't see how screw terminals are any better or worse than a wire nut and a pigtail though, provided it's a quality receptacle and they are torqued properly.
