Kvetch came about when a bunch of WP developers decided to leave the project due to their opinions not being listened to and started up Habari. It was basically window-dressing to make it look like Matt was interested in feedback after all.

It's tough getting Automattic to do wordpress.org maintenance (it doesn't pay the bills) so my guess is that the kvetch 'feature' will either stay the same indefinitely or eventually be deleted. Unless they can outsource it to volunteers, like they did with theme reviews. That could work.
