Good and interesting info.
Modeling structures with that feature would add depth to the scenery, however, the catch is that you'd have to be prepared for criticisms from well-meaning modelers and/or visitors.
In keeping "selective compression" in mind, having one structure emitting a prototyical "interior glow" may complement the scene. Having multiple structures with leaking light, however, may turn out to be more of a destraction to the human eye even if modeled after prototypes.
Just my thoughts
"I like my Pullman Standards & Budds in Stainless Steel flavors, thank you!"
I've seen some corrugated steel buildings with panels of corrugated fiberglass added to provide natural light to the interior. That, too, should make an interesting effect if modeled.
Not something I can do myself. The similar buildings in my modeled area were unpainted, well-weathered wood.

Been meaning to share something that occured to me a while back one early morning at work. The plant I work in has a number of production buildings which had been steel corrugated siding over steel framing with no inner walls, insulation, or other type of covering from the inside. They are simply weather protection for process equipment. We've recently re-sided these buildings with corrugated fiberglass siding and it struck me how with the new fiberglass siding, the buildings "glowed" from the lights within, the very situation we work so hard to avoid on our model railroads. Obviously not prototypical for many building materials, but for more modern industrial buildings, a little glow may be perfectly accurate. Just be sure to add several bulbs inside to similuate the various lights throughout the structure.
