Well, I think people who use ftrace are m,ore likely to look at kernel messages than most... So what would be more interesting is if there's some distro support for showing kernel notifications.. I see new notifications for calendar events, for devices that got mounted, for a lot of things - so I'm really wondering if somebody already perhaps had something for specially formatted kernel messages..
