Worth a conversation about a follow-on, do we want to update our internal vars & service names as well:

// now a credentialResource?
var bindingResource = {
  group: 'servicecatalog.k8s.io',
  resource: 'serviceinstancecredentials'
};		    

// CredentialService?
angular.module("openshiftCommonServices")
  .service("BindingService",

// etc.

Could prob make a tech debt issue

Good question. We still call it "Binding" in the UI, and we will eventually make pod presets to bind to apps as well.

No strong opinion then, unless we update to "Credentials" in the UI at some point.
