The flip side of my impromptu "rule" is that you can drop the "careful" part as long as you are comfortable with a little or a lot of mess. Obvious common sense lowers the tolerance. I wonder how others set their tolerance? My perspective is that most OO hoerarchies don't go too deep. I've seen 4-5 at rare extremes. Around 2-3 is common. I'm sure someone has encountered 10 or more. I shudder to think how well that turns out in practice.
