OK, I see your question. For T/S lenses EXIF data would allow programs like DXO to correct image aberrations. I use DXO all the time and it does indeed improve images quite visibly. I'm not referring to effects, just corrections for things such as chromatic aberration, vignetting, differences in sharpness across the image field, etc... With T/S lenses such aberrations can be exaggerated because the lenses rely on a bigger image circle. For the type of work (i.e precise, exacting) one would use a T/S lens for it would seem very appropriate to have the ability to maximize the quality of every last pixel. At this point you can't even apply the same kind of image correction to a T/S lens that you can to a CoolPix lens.
I think the great thing about programs such as DXO is that they do a fantastic job of image aberration correction with no work at all - which leaves you free to concentrate on photography rather than technology. I see no conflict or disadvantage at all - in fact, quite the opposite.
