We use impersonation as cluster admins to elevate access to customer secrets and certain resources, and kubectl supports this with the --as or --as-group flags. Currently to use the cilium cli tool, we have to hand edit our kubeconfig to add
as: <user>
for our user, and then remember to remove it afterwords. Supporting impersonation directly in the Cilium cli tooling would make it much safer for us and align cilium with other kubectl flags.
