I can't imagine people will start using SO_REUSEPORT by default, since the "performance reasons" are a happy accident of having a hint (that the process wants wakeups distributed across all CPUs). I'd rather get that hint in another way- perhaps by sharing an epollfd with multiple processes. I would however like SO_REUSEPORT to run experiments: Right now we use iptables/tc to direct some traffic at "new versions" of some of our systems so we can run tests with live data, but connection tracking for localhost is lame. I'd much rather use SO_REUSEPORT.
