It sounds like Norwegian reforms didn't as much as introduce change, but properly reacted to actual changes in the language. Which IMO is the best way to do those reforms and changes.
Both yes and no, they introduce actual change for large parts of the population, but the introduce changes that reconcile differences in dialects or reconcile inconsistencies. Importantly they back off when a change doesn't get traction, and are prepared to wait and try again later rather than try to force through drastic changes too quickly.
