I wonder if that is there to prevent the vibrations we are partially feeling at 1800 rpm.

It doesn't bother me enough to do anything about it. Just curious.

per the dealership they can rebuild it but it’s not a guaranteed fix.

I have the bulletin from the same issue on the 470’s.

I do not think it is a problem and I opted not to have them rebuild.
