All that would reasonably be needed is that it is permanently prevented from being used again, so it is an historical oddity by the time of the later shows. There would be little need to mention it any more than one would mention camel riding. The only issue for continuity is if they just stop using it because of an environmental analogue, or because of its general negative effects on the navigator. Because then the question comes up of why Voyager didn't try just one jump.
