nit: If we support any other special verbs in the future, we can write this like the following.

    specials = []schema.XXX{        
          {
              Group:    "extensions",
              Resource: "podsecuritypolicies",
              Verb: "use",
          },
      }

for _, s := range specials {     
    if resource.Name ==  s.Resource && verb == s.Verb {
        return true
    }
}
