  My experience is that as long as a rule has only one exception, people are pretty good at keeping on top of them. But that always leaves you the question of whether you want to burn that exception on the current project or save it for something better. Which then makes you very nervous when your coworkers start getting clever ideas and trying to volunteer (over-engineered) things as the exception. In the same way the best leaders often didn't want the job, the best exceptions are the ones you accept grudgingly, not enthusiastically. Much more recently I realized that this phenomenon of One Rule, One Exception falls under the umbrella of - or perhaps explains the effectiveness of - the Rule of Three. Two exceptions are bad, and work is partially pre-empted to correct that problem.
