Using studs where the highest stressed middle is not threaded makes engineering sense.

Not having the end fasteners leave the aluminum cylinder at 90 degrees makes engineering sense.

or perhaps brainiac spreadsheet obsessed MBA’s in management never taught whiff of “engineering sense.”

Of course all this now corrected with French top management at Stellantis.
