Definitely. If a reviewer spins up Theme Sniffer and sees that you have 0 warnings or errors, that puts you on a pretty fast track to getting approved and set live assuming the other things that must be manually checked are in order.

Seriously, we've tried to push this plugin to theme authors, but it's tough to get the word out. If theme authors were using it and cleaning up their themes prior to submission, the queue would have a turnaround of less than a week, I'd wager.
