Right, this is a different semantic though, and there are different messages
for them as well. Also hold has a bit more information and is still mostly
informational:

  hold: Please stop sending, i'm not listening anymore, you're just wasting
        bandwidth if you keep sending or if you're going to send now.
  unhold: I'm listening again, you can start sending again.
