Delta eliminates changes/refunds to award tickets inside 72 hours

According to this post by Wandering Aramean, Delta will no longer permit changes or refund miles for SkyMiles award tickets that within 72 hours of departure. The new policy took effect on August 15th and applies to all members including elites. What this means is that you can no longer hold a reward booking with the hopes of changing or canceling it last minute. Apparently there were hundreds of thousands of seats that went empty due to people not showing up for their reward flights and then having the miles redeposited into their accounts. Delta has taken a lot of heat from frequent and even infrequent flyers to many of the changes they have instituted recently and would like to know from our Canadian SkyMiles readers, what do you think of this change?
