Don't quite get that.
Anyway, less is more. Strip it down, keep it simple and focus on the work.
Back in the days when the image quality of zoom lenses was lower than I could accept, I carried three bodies and three fast prime lenses when shooting fast moving events (like stage shows) so I did not waste time changing lenses. I had a wide angle on one body around my neck; a telephoto under one arm; and a normal prime under the other arm.
There is credence to your question about what difference does it make because today, I do something similar with three fast zoom lenses: 14-24mm f/2.8, 28-70mm f/2.8, and 80-200mm f/2.8 (my "Holy Trinity") on three bayonet-mount Nikon bodies.
