There's no benefit to it only being able to reach some small group of people. There is benefit in being able to include only a small group of people in a particular conversation, but that does not require no interoperability, only a concept of groups and permissions and access controls. In fact, it is completely orthogonal to the lack of interop.

If something can just be locked to only talk inside the intranet/VPN it's better from something that can talk to arbitrary people the world over and is only configured not to via its own groups and permissions inside.
I thought we were talking about Slack, and several other hosted services, which don't fit the description you've just given, at all. But, for a self-hosted chat service, then yes...that's a benefit.
