For me, it would depend on how much quilting I was going to do in that area. The more quilting there is, the less stress is put on the seam. I have gotten some quilt tops from my sister with seams like that. I just always make sure to do lots of quilting over those seams (by choosing a freehand pattern such as loops or meander, which turn out great for me).
Another thing I have done when the seams are actually pulling apart is iron a lightweight fusible interfacing to the wrong side to secure the area. This does not show up at all in the finished quilt, and in my opinion requires being quilted over to fully secure the reinforcement, but has worked really well.
