They don’t directly mention it, but as I recall after that episode traveling at high warp speeds was greatly diminished and warp speeds above certain thresholds were only used in emergency situations/required special authorization. So not completely abandoned but they certainly didn’t build on the premise, which is a shame because I thought it was one of the cooler plot elements that was introduced in the series.
