Even if it was global, if you read the details, this isn't really a change as it is just explaining what they're doing. They were doing most of these things before - all they're saying is 'we'll try to be better at telling you what we mean'... which is good, but doesn't fix the actual problem - the way they do repair.
Most of this is 'we'll provide evidence that we didn't do more damage' - it's about blame mitigation, not actually just fixing the problem. Most companies just fix the warrantied problem and don't even discuss these issues. I mean, who sends their handheld in because the case has a small ding (that conveniently requires replacing the entire display - out of warranty)?
The exception is the reduction in overreaction to cosmetic damage, which is good, but that's what they already said they were going to do in response to the original YT video.
