I think you'd have a better chance getting a response from Obama on the issue before the CFTC chimed in. The limited experience I've had with the CFTC (and other financial regulatory entities) implies that they want to maintain the broadest reach possible and will rarely, if ever, offer clarifying statements.

We have literally asked for clarification on sections of regulations before and offered several scenarios asking which interpretation was correct. The response : "we can't offer an opinion on that." Even though they would be the ones enforcing it.
