Question about balancing rotating assembly

As for the V-10 damper issue etc.....I'm well aware a lot of engine have the damper very well secured. I'm also aware a lot of engines have them far less well secured. For example, the mighty Slant Six - made by the millions in a hundred applications - in almost every case used no bolt at all. They just pressed the damper in place and off it went.
Now you've put something in my mind that I am going to have to think about... LOL. There has to be a good explanation.
