This works out to be more efficient in common cases where policies change much less often than workloads.
This only applies for selector-based policies; namespaced and global policies can be handled without needing to list them out in the Workload API.

## Redirection

As ztunnel aims to transparently encrypt and route users traffic, we need a mechanism to capture all traffic entering and leaving "mesh" pods.

## PeerAuthentication and the Waypoint Proxy

(Note: this section is not yet implemented and is dependent upon discussion in the [ztunnel hairpinning doc](https://docs.google.com/document/d/1uM1c3zzoehiijh1ZpZuJ1-SzuVVupenv8r5yuCaFshs/edit#heading=h.dwbqvwmg6ud3))

Goals:
- Improve upgrade experience: users should be able to gradually roll upgrades, with proper
canary deployments for Istio components. It should be possible to deploy a new version while keeping the
stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select

This document is an overview of how the operator works from a user perspective. For more details about the design and
