How so? In most lenses with central shutters, the shutter is directly in front of/behind the aperture. Some even use one diaphragm for both functions.
From an optical perspective, a lens with and without a central shutter are basically identical.
Examples of this are large-format lenses, whose cells are routinely used in both barrels and shutters without any optical modifications at all.
Great aperture and central shutter don't fit along well. A real world example: Zeiss lenses for Hasselblad. Lenses for F cameras get larger aperture than those for C cameras. Wonder why?
