How low are we talking? Cryogenics low, hamburger patty low or keep the lettuce fresh but not frozen low?

I say yes, with everything considered a wet environment, and penetrations sealed.
Lol… how’s about keeping meat not smell bad?

Cryogenic low and then there's a chance to have superconductors

They can and frequently are.
I agree that the penetrations need sealed for the same reason you need to seal a penetration into a building. I disagree about the wet environment part. One of the driest places you'll ever find is the inside of a walk in cooler.

Even condensation, say in a refrigerator vs a freezer?
Wouldn't there be a dew-point somewhere in the penetrative wiring even sealed?

I don't know about the science of it but a walk in cooler or walk in freezer, you can make jerky inside them.

It's not an ice cave.
You're right, and I don't have a lot of real world experience in electrical installation. But I do have a lot of real world experience.
I would just wire it as if it were a wet location. I think that at some point there is a very real possibility that it will start having problems like every refrigerator/freezer I have ever owned, where it will stop cooling efficiently or someone will leave the door open and water will start condensing on every surface like on a glass of ice water on a humid day.

There is a very real possibility your roof will have a leak. Are you going to take similar precautions?
No. But that's just me making decisions on likelihood or probability of what I think could be an issue. We just have different risk assessments.
