Like everything else in the "STANDARD" (not Code) It's only required if the AHJ say's it is. We have jurisdictions here in the west,( where water law has more lawyers than any other kind,) and water authorities don't want the full forward flow ability to be installed, because it uses to much water on a connection that's un-metered. Usually the Fire AHj agrees.
