I don't think it's a cop-out. It just explains (probably correctly) that a petition is not a good medium for expressing the problem and talking about possible solutions. There is a link http://www.uspto.gov/aia_implementation to the place where this conversation is already underway, and which you are welcome to join in.
That's most definitely a cop-out, or more accurately "the run-around". It tells a pile of people who have already expressed their views to wander elsewhere and express them again, deflecting the original effort. That blunts the force of the original response. Oh, and the linked site wants public comments within the next week or two.
The site's been up for months. It seems like anyone who actually cares about the issue would have been able to find it by now, since it's on the USPTO home page, first link under the IP Law & Policy section. http://www.uspto.gov/
