Never had these up north and we actually survived.

The hose won’t explode IF you keep the device on, as that’s one of the things it’s there for. Release an overpressure if the water in the hose expands from warming up and expanding. The over pressure needs someplace to go. Without it, the hose will swell and may cause damage to your hose. But the device is designed to keep now contaminated water from flowing back into your house clean water supply.
If your water supply pressure drops, it will prevent this water from backflowing into the clean house water supply. It’s there for your health and safety.
Depending on type of backflow design, water spraying out may indicate a failed rubber gasket, or it may be normal.
All of our new builds around me do spray a lil when the water is turned off and a hose is attached.
Like others have mentioned, keeping your hose sprayer on while turning the water off should minimize this spraying.
