I think the idea is a good one. It allows a distribution to take more proactive measures before services just start dying randomly later. I could see this nicely wrapped up with some kind of GUI dialog presented to the desktop user announcing impending doom, too. > Uevents should not be used for error reporting Not as currently implemented - but I think the idea of having kernel events for this kind of thing isn't a bad one, nor is the idea of listening on a netlink socket for news about them rather than writing library code to poll whatever procfs file and parse its content.
