This is my family room floor. Yes, that's subfloor. No, it's not a new decorating trend. The toilet in the kids' bathroom overfilled, probably for a few hours and damaged the carpet in one bedroom and the wood floors in the hall and family room. The vinyl in the bathroom had to come up so the floor could be completely dried. We'll also need to replace the cabinet due to water damage at its base.
It's all about perspective.
