I see track lighting being put in modern homes for certain applications including very high ceilings that are angled, so I'm not sure the question here unless you are talking about a specific style of track lighting.

I googled MCM lighting & was surprised to find some track lighting included. I am remodeling my kitchen with a 1950’s style & could use a linear size light fixture to avoid dark areas.
