only wins where a pathological case is used for the iptables counterpart (e.g.<br>
tons of single IPs as individual rules and without ipset). It is a disaster<br>
that it is purported to be the iptables replacement, just for the syntax and<br>
non-essential whistles such as updating rules in place or something. And<br>
personally I don't prefer the new syntax either. It's the systemd and<br>
pulseaudio story all over again, where something more convoluted, less reliable<br>
and of lower quality is passed for a replacement of stuff that actually worked,<br>
but was deemed "unsexy" and arbitrarly declared as deprecated.<br>
