It's not that people think they don't work in the cold, it's that they are less suited for the areas or days of extreme cold.

Which is why you have a backup system. I have a net zero house in Saskatchewan, Canada. My Carrier heat pump will operate to -15C, and switches to electric heating coils in the air handler if it's colder outside. It's a rather extreme climate here, but in most other places, you'd be fine with some baseboard heaters as backup.
