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.

As a result, each individual controllers should simply wait until informers have synced, then run the queue to start processing things.

A queue is used to give a few properties:
* Ability to serially process updates received from a variety of different sources. This avoids need for other synchronization mechanisms like mutexes.

  //   request resource.
  //
  // The `apiVersion`, `kind`, `metadata.name` and `metadata.generateName` are always accessible from the root of the
  // object. No other metadata properties are accessible.
  //
  // Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible.
  // Accessible property names are escaped according to the following rules when accessed in the expression:
