I'm well aware of the compromise, but if I can't get rid of the de-centering by stopping down, then there's really no point in buying it. I don't expect to be able to use such a lens wide open for anything but emergency shots. There's no free lunch.
If the lens is sharp at f/8.0 throughout its zoom range and across the frame then I'd be more than happy. When I'm traveling I usually get by just fine with shooting around this aperture value.
