I like overkill: that stuff is easier to maintain and requires it less frequently. I took out one of Ward's monsterous anchors (to repair it after someone chopped the other half of it, among other reasons) and it was super easy to retrofit. I definitely appreciated the larger holes when I was fishing out the old sleeves and prepping for new hardware.
For some reason, I am conjuring up images of the single bolt anchors on the third flatiron....now those might be overkill....
