"...Or conversely, the positives if the rule was terminated?..."
Well the manufacturers do the testing and make their power claims. The FTC only has the ability to enforce the rule but not sure they ever have used this particular rule. Responsible manufactures do the testing per the FTC rules and that costs time and money for very dubious results. Even with the current rule I've had 100 watt amps that seem weak and 25 watt amps that had plenty of power. It is a useless specification that is no help to the consumer.
