I think it just depends. For people who are running a log scraper
anyway, a message would be better than a statistics counter, because
it's one less thing to check. For people who are running something
that monitors the stats views anyway, but perhaps not a log scraper,
the counter is better.
Overall, I don't see much reason to tinker with this. If we had no
reporting at all of this condition now, I'd probably be mildly more
supportive of adding a log message than a counter. But since we've
already got something and there's no real problem with it, I'm
disinclined to make a change.
