Thanks! To be a bit more verbose about the rationale: Changing the default behavior is generally a bad idea, unless strictly necessary (e.g., if the previous default behavior was buggy anyway), because it may break other software. Please try introducing behavioral changes via new options. That way, dependencies will still work fine and anyone who wants to use the new behavior can explicitly do so via a switch. I could work around this by checking ss' version, but that turns out to be a pain, too, because ss -V reports something like this: "ss utility, iproute2-ss150413" Not exactly a "friendly" version like "3.19.0" or "4.0.0" to check against...
