I certainly agree. I'm relating more to my own personal experience, where I do have a heated garage and/or can plug in at will. As for cold starting when not being plugged in or indoors, that's what got me started running M1 5w30 exclusively a few years back. As an aside, it was really nice having the M1 and an oil pan heater at the same time.
The only real issue I have is that we might be being a little too OCD about the whole issue. I like the idea of having the thinnest possible oil in the pan at startup. That's a no-brainer. However, even in the Great White North, our roads aren't littered with vehicles disabled by spun bearings because they used a conventional 5w30 or 10w30 in the winter, either.
Aside from that, when it's -40 out, the weather will focus you on the real issues, real fast. Running the freest flowing synthetic in the world isn't going to help you when your battery is on its way out, your cables have been neglected, your engine is terribly out of tune, or you're running a severely diluted coolant mix and it's frozen solid.
