These ignorable-gate nodes, rather than forcing the value passing through to be zero, are behaviorally equivalent to identity operations; however, they can semantically mark a value as "unused". This can be applied to, for example, explicitly limit the load-enable of a pipeline register. PiperOrigin-RevId: 933919517
