Sigh. Varlink is designed for IPC, so the expected data rate is maybe hundreds of messages per second in the worst case. JSON can be parsed at 3 Gigabytes/second [0]. Even unoptimized stdlib parsers in scripting languages get 50 MB/sec. That's more than enough, standard library support is much more important for a project like this. And if there is ever a reason to send tar archive or video data, there is always "upgrade" option to switch to raw TCP sockets, with no JSON overhead at all.

In Varlink – IPC to replace D-Bus gradually in systemd
