weeks prior to a new release. The `istio/istio.io` repository does not get branched until the release is ready
for publication.

This document outlines getting in new features after a new branch has been cut and the process for getting a PR
merged in before and after the first public release.

However, this has one glaring issue: how do we get the traffic to the remote proxies, while maintaining the zero-trust properties that Istio is built upon?

A secondary goal was to enable a smoother on-ramp from "Zero" to "Getting some value".
Historically, Istio had to really be consumed all-or-nothing for things to work as expected.

// 3. Creating iptables rules inside the pod's netns
