I'd be more worried about a GD wiggling down inside a sleeping bag that is attached to her than a quilt.
Each to their own (advice and guidance based on their comfort levels and beliefs) but we've always had blankets/quilts in their cribs. They wore feeted pajamas if they wouldn't stay covered up.
Our 2 sons also covered up their faces (and still do at 25 & 29) when they sleep.
I want quilts to be used and worn out if possible :)
