Your quilt is precious. If you know that you have quilted at least 2-4 inches apart, then it's fine. From what I can tell, quilting magazines promote quilting all over the quilt, but that has not always been the way it's been done. I do not like to see quilting overdone, it distracts from the fabric and the pattern. I have seen quilts that I actually can't tell the pattern because they have been quilted so heavily. None of my vintage quilts have this done on them. It is your choice what you want to do, but if you follow the batting directions, you will be fine.
