No, that's exactly what I want.
The use case is this:
I (hypothetically) run an underground burlesque troupe that broadcasts edgy clown shows out of an abandoned warehouse. I have a camera there that broadcasts a feed of the warehouse to people who have paid me to connect to their various televisions and monitors.
When someone pays for Burlesque TV, I come up to their paid and link their monitor to my BTV hub.
However, I also use the warehouse for meetings of my secret club, which I do not want to broadcast, so I only turn the BTV feed on during shows. In the past, I would handle that by "setting output to none" on the BTV hub when the show was over and "setting output to all" when the show starts. Now the only way to achieve the same end is to uninstall the hub, which means performers may or may not be able to run the hub system when I'm not there.
Alternately, I could have two hubs -- one which gets the feed and one which distributes it -- and selectively scan-unscan those two hubs to act as a switch. I'm okay with that as a solution but it adds extra bloat to networks, and there are other "switch" use cases where you might end up adding a lot of hubs just to have the on-off functionality in multiple locations. (Sorry to be vague, I just don't want to put out too much ICinfo.)
