As others have mentioned, it will get flimsy with use. What you might want to think about is the area you live in or where the quilt will be. Bugs love starch and when you go to store it whether in a closet or a container, might the bugs find it and make a buffet out of it? I know in Florida or any humid area, bugs are there no matter how clean you might think your home is. They're sneaky and will find it. I use starch as well as Elmer's Glue on my quilts during assembling so I wash mine once its finished. Plus I want to make sure it doesn't bleed before giving it to someone. Rather have it happen to me instead of someone else and they freak out thinking they've ruined it.
