Maybe the rule should be "don't fix it unless you're capable." Then you could have some guidelines for when someone is capable. Some of that might have to do with skill/experience but even with my own code I don't like to make fixes unless it's related to a feature I'm in the middle of. Otherwise I'm at risk for making subtle functional changes that I don't have any capacity for understanding or predicting.
