		Use:     "ecds [<type>/]<name>[.<namespace>]",

		Short:   "Retrieves typed extension configuration for the Envoy in the specified pod",
		Long:    `Retrieve information about typed extension configuration for the Envoy instance in the specified pod.`,
		Example: `  # Retrieve full typed extension configuration for a given pod from Envoy.

In our testing, even the most generous representations give custom types a 10x edge (in size, allocations, and CPU time) over Envoy types.
In addition, they are more clear and strictly typed; using Envoy types would require us to put a lot of information in untyped `metadata` maps.

With this in mind, Ztunnel supports two xDS resources: `Address` and `Authorization`.
