The operator kit had more utility originally when the operator was creating and managing the TPRs and CRDs directly. Since the CRDs are now created from a manifest and no longer by the operators, the utility of operator kit is limited to the controller watcher. Since we are moving to the controller runtime we simplify the code to make the transition smoother. Now there is only a simple WatchCR method that will need to be replaced as we maek that transition.
