Then if there is a problem you just log it using whatever format is in effect and don't change the setting. Then the worst that happens is that logs show up in a format log processing isn't prepared to accept. That being said, I think I fall in the “just start putting more digits in the log” camp, although it is conceivable the counter arguments might be convincing.
