I don't think restarting an application should have effect on how it's
routed, so I think we should keep the original choice.

Yes, if I'm going to work on this, I plan using the message subsystem.
But if I'm going to work on this, I will first work on improving how
configuration files are handled, because the choice of disabling jack
detection for a port should be saved on disk, and I want to use a
configuration file for that in a particular way that isn't currently
