No worries! Updating the map to reflect current construction and conditions is fine. I personally haven't risen that route in months. Back when I made that update it was a perfectly safe route, even though the separation from traffic was achieved through temporary means. Looking at the Strava global heatmap, it appears like this bike track is still a busy route, which suggests that many people are finding it transitable. You may find the "construction" tag useful as a way to temporarily disable segments of the path, if you want.
