@breadsmasher I have no idea how Tor works. In this case I would say most peers would have no problem disclosing a public IP, but it could have benefits in making resources in a private network accessible and as long as the endpoint can be reached those resources would be hosting provider agnostic.
I would say this is less about hiding user activity than it is about logical networks, abstracting away the hosting provider and allowing to knit together self hosted services, regardless of where they are hosted.
