Well, that's one example! Could you find any other?

Bolting should be kept to a bare minimum, consisting only of great lines.
To this I fully agree.
Unfortunately, one person’s judgment about the line potential as a new route is often not enough. It needs some traffic, and thus time.
If it is a bad line, maybe one should do it on tope-rope.
I climb ALL my new routes first either on top-rope or glogging, usually several times. And not only to try the climbing quality, but as an important part of cleaning up -
to try and break down everything which would go down under a full body weight. Only after that, it's time to figure out the bolt placements.
At many places, putting up a top-rope is at least time consuming, often very hard. Do many out there know how to fix top-ropes at Örnberget, for example? And that's not too hard if you know. But if not, you could easily spend half of your climbing evening session on equipping one route.
