Many legacy hose and plumbing fittings made of brass and other metals can split in very cold temperatures if they've been left connected outdoors all winter. They'd be ruined in the spring thaw. I've seen plastics crack under similar conditions.

The valve is at the far end, 12+ inches into the house (the water on the other side of the valve is never cold enough to freeze). And the pipe is angled ever so slightly downward, so gravity ensures that any water left after closing the valve flows out. That's why you can't leave a hose connected - it leaves open the possibility of preventing water from draining out before it freezes.
