I wonder if another reason why a lot of the current crop of hyper-performance fast lenses is getting bigger is that it's easier to build a lens with a larger image circle and leverage a smaller sweet spot of the optical lens. All those edge aberrations end up outside the region covered by the sensor and hence flatter MTFs, less corrections required etc. It would be easier to design and build this way, albeit at the expense of size.
Just a thought. It certainly applies to using existing larger format lenses on smaller format sensors.
