I think the theory is sound, that as stress is put on the quilt, the fabric will give way before the thread, but I'm not sure that it matters. If you're putting that much stress on your quilt and use cotton thread, the fabric and the thread will break. Unless you're making an heirloom quilt that you want to outlast you, I wouldn't worry about it too much. JMO.
