All the the hate for json here, but at the bottom there is a bridge screenshot. Varlink is designed such that it can trivially be piped across different systems and be maximally interoperable due simple to parse and encode protocol. We might end up with some IPC interface that a lot me tooling can understand. Eg imagine that instead of some daemons supporting sighup to reload, they could also confirm that they reloaded, provided Prometheus style metrics etc
