I've not had it happen, but I've only been quilting for 6 years so my quilts are all relatively young. But I will say that yes - I've seen some OLD quilts where the seams have raveled and split. OLD as in antique.
So the question is ... how long do you EXPECT your quilt to remain pristine? It might then be worth it to you to consider using a wider seam allowance. Although I would think there are other factors too that should be considered if one would expect a quilt to last several generations ... guess I never gave it that much thought!!
