We saw the clarification this morning.
If I'm interpreting this correctly then our configuration is legal as our arm never extends further than 15" outside the robots frame perimeter. This works because the entire robot revolves around the arm pivot and thus we never violate that configuration.
We designed the arm with the specific length in mind so we could manipulate the defenses during game play as well as hang. I'm happy our design remains within the rules for now, however it is odd to be so restrictive on a more difficult task.

I think the assumption is that our arm is very long but it is indeed only 15" longer than the frame perimeter. If it were not then we would not be able to use it to manipulate the defenses.
/Edit***** I should say close enough to prove a point. If our bot is an 1" or so out of spec. we don't typically rectify. We only ever seek to be mostly FIRST legal :-)
