As a dweller of a cold place in the USA, F is pretty handy because "freezing" isn't terribly cold. Having 0F be "actually quite seriously cold" is useful.
My parents care a lot about "przymrozek" - which is when it gets sub-zero C at night and you need to cover the plants and close the greenhouse doors and put a heater there so the plants survive. They give warnings in radio when this happen outside of regular winter months.
There's also special warning for drivers if it was sub-zero because then the water on the roads freezes and it's very hard to break.
I'd say it's way more important a distinction than anything that F makes obvious.
