Right now, only a little bit. In the future, very likely.

Systemd will eventually be functionally overloaded with network requests much like svchost.exe is (over)used on Microsoft Windows. That is just one example.

This is also useful for folks to catch browser exploits that escape the sandboxes and make arbitrary connections to bypass privacy mechanisms such as Tor or other forms of proxies. i.e. dns leakage, tcp leakage via websockets, etc..

There are many other examples I could provide, but I have limited time right now to respond.
