About 14 days out seems to be when they free up inventory anyway. First off it goes to waitlist but then (if there is no waitlist) appears as open inventory. This hasn't really changed in terms of what options exist, what has changed if the fact that at 14 days you get a definitive yay/nay and for one I'd rather know that. With the flexible search you will be better able to see that availability too and while you may not be able to get the day you want SQ seem pretty good at making what is unsold actually available about 1-2 weeks out.Knowing for certain that your waitlist for an award booking has been unsuccessful doesn't leave many options for alternatives 14 days out. I agree that this is not that helpful really.
Noone has mentioned the discounted redemptions for last minute travle, this may be interesting too.
