Have you looked at the angle of the rounded more than 6 blade apertures? The curve and angle can introduce more sticking and error and shutter failure that need repair more often, I think it has to do with the mechanism and how long it will last without repair than anything, it doesn't cost them THAT much more for 8 blades then 5, it's that you introduce more components that need to be smaller to function and could easily break more often. I don't think it had anything to do with the aesthetic.
