The fridge box is fairly insulated. Temps in my home are consistent all over plus or minus a couple degrees. I think you've overstating the case a lot here. Even with the oven running it doesnt seem to affect the fridge too much. Heck in a lot of warmer climates people leave a spare fridge outside where its battling non-climate controlled air.
In the winter your fridge's waste heat is warming up your kitchen, so if anything, its a bit of a bonus those months.
The only thing I think we could do with fridges is put in a system that pulls cold air in during the winter but that's sawing holes into brick and yet another thing to worry about in regards to mold, critters, moisture, filters, fans, etc. Its just not worth the effort or cost.
