Why are fridges in cold climate countries not mounted into the wall of a house so the ambient air could cool the inside?

A household fridge is a small energy consumer and it’s only cold outside for part of the year with no control over what temperatures you get exactly. So a fridge sized hole in a wall is just a very bad idea. Also, the refrigerant has a working temp range, if it’s too cold outside, it doesn’t vaporise and can’t pump heat.
To do something like it, I would rather have extra coolant loop in fridge, run it to radiator outside and when it’s cold enough outside you run that coolant loop rather than the normal fridge heat pump. It would make for a quieter fridge for part of the year and it would save energy, but not much and it would require a very custom fridge that just doesn’t exist on consumer market.
I wonder if industrial market has anything of the sort….. most likely yes.
