I'd agree that's it a component, but not a necessary one?

One of the strongest senses of liminality I've experienced has been being in a middle school at 9 PM when almost nobody else was in the building. I was a poll worker and we were wrapping up for the evening, so there were only 4 of us there. Doing things like walking to the bathroom through the empty school felt very strange, because I was surrounded by evidence of people using this space and yet there were none there.

A different place I felt that way was when I lived in Flint, MI. I'd walk to work early in the morning, and I'd pass the Flint Institute of Arts, which was at the time one of the few places in the city with any money, so they had a very well maintained and manicured outdoor space (evidence of people), but I never saw anyone.

On the other hand, airports and hotels are classic liminal and they're usually peopled.
