Does Hasselblad even have a T/S lens for the H platform? In order for this to work, the shift amount and tilt angle would all need to be recorded for use in the correction software, as well as focal distance and aperture. I don't believe this will happen anytime soon!
Interesting point.
I use DxO occasionally, mainly on certain Canon lenses like the 24-105mm and 14mm where there's complex distortion issues which DxO fixes more convincingly (and quickly) than doing the job myself in Photoshop. However, I'd really appreciate some DxO asistance with the three Canon T&S lenses, but no deal, as you say DxO can't handle the uncertainty of lens movements and say there's no fix in prospect. My Hasselblad dealer says that at least one H series T&S lens is in development (and has been for at least 18 months) so it will be interesting to see if they deliver a T&S optic with digital correction.
The trade off for retrofocus lens designers between distortion and resolution is clear. I use the Hasselblad V series with a Phase One back and a selection of wide lenses, the 38mm Biogon (non retrofocus so you get zero distortion, high resolution, but no lens movements and quite noticeable vignetting), the older 40mm Hasselblad lenses (moderate distortion, very low edge resolution, moderate movements possible on a Flexbody camera, moderate vignetting), and the new 40mm IF (very severe distortion, very high resolution, quite large movements possible on a Flexbody camera, moderate vignetting).
I guess you pays your money and you takes your choice, but if T&S digital correction ever becomes a reality then we could walk down both sides of the street at the same time!
