There's no "craftsmanship" here. These are mass produced, factory made instruments. The less people have to touch them, the better and cheaper they'll be. I'll go one further. These basses aren't just CNC routed, they're CNC cut and shaped. I'm sure Fender knows what they're doing. The ugly hole doesn't show.I just don't see why they would have to have that hole though. Plenty of basses are CNC routed and there's no ugly hole in the body to show for it.
Fender craftsmanship at it's finest
There are people who fill the hole up with coins, so that could be an option if you decide to go nekked
