Especially if those users don't seem particularly concerned (or simply don't check the updates entries religiously)?
This is why I suggested that there should be an update log entry for these changes. The entire route got renumbered. That's a news worthy change.
I didn’t change any point in use. Thus, not news worthy.
You're missing the point. The ENTIRE ROUTE had it's visible labels changed. That means it's 150% a news worthy change to let people know about that. It doesn't matter if you didn't 'change' any label in use to another location.
Whenever a route has all it's labels changed, it's always been considered news worthy, even if only 2-3 people have been on it.
Examples:
2025-02-13 (USA) Connecticut CT 11 ct.ct011 Relabeled exits from sequential to mileage-based.
2025-02-13 (USA) Connecticut CT 2 ct.ct002 Relabeled exits from sequential to mileage-based.
CT-11 above is a perfect example of this. All labels got changed, news entry added, & no 'in-use' point changed.
