I'm not really sure what else there is to discuss on this one. Unless the queue reaches a point where newbies can't get it done in a reasonable time, there's no reason for SE to make any further changes. It's job is to get newbies through the MSQ. If it does that, it's working as intended.

So if/when we see massive queue times, that'll be a thing. Predicting them has aready been done and is old hat now.
