Heat pumps are specified with significant margin and/or backup heat sources.

The numbers above are the 1:1 point, which doesn’t mean it stops working. It just means it’s similar efficiency to an electric heater at that point.

“Freeze to death” is an extreme exaggeration.

This is spot on. Some mini split heat pumps effectively become base board heaters with a fan when their efficiency falls off. You'll be uncomfortable, but you won't freeze to death.
