Agreed, more clarity would be a good thing. To keep things in perspective, you can only get so far trying to protect people from themselves. This past Friday I found a GE 30 Amp single pole breaker protecting #12 conductors (and not feeding a motor). The same panel probably contained 4 different brands of breakers. Some of the breakers had more than one conductor under the terminal screw. Any of these common violations are more likely to cause a problem than the scenario this thread discusses.
If the AHJ is agreeable, go for it, and sleep well. Maybe the code commitee will catch up in 2014. By then, there will likely be advances in the solar industry that won't be addressed until 2017. So it goes.

Just being devil's advocate here... I'm with you, but we need more clarity and less room for interpretation on this matter.
