* The Credentials controller is responsible for reading TLS certificates, stored as Secrets.
* The Kubernetes Service Discovery controller is a bit of a monolith, and spins off a bunch of other sub-controllers in addition to the core service discovery controller.

Because of the monolithic complexity it helps to see this magnified a bit:

To make ztunnel more transparent, the original source IP address will be spoofed.
Additionally, `splice` will be used to make this proxying more efficient when possible.

For traffic in the mesh, things are a bit more complex:

1. If the destination has a waypoint proxy, we must send to it to the waypoint (using HBONE).

additional RBAC permissions.

- simplified label and chart structure.
- ability to run a pilot dedicated for the gateway, isolated from the main pilot. This is more robust, safer on upgrades
and allows a bit more flexibility.
- the dedicated pilot-per-ingress is required if the gateway needs to support k8s-style ingress.
