There is no reason what so ever to mount a lens "precise".
And you wanting to not accept "equivalence" and therefore introducing "equal quality", that is just funny. In your world, one can't compare a Nikkor AF-S 50mm f1.4 mounted on a Nikon D750 and a Sigma 50mm f1.4 Art mounted on a Nikon D750, because... the lenses are not of equal quality, don't do everything the same.
In your wold, we can't call that Nikkor 50mm f1.4 mounted on FF equivalent to that Sigma 50mm f1.4, because "they don't render the same", "they don't have the same sharpness".
Funny how equivalency, which touches on the two fundamental aspects of lenses (FOV and DOF) in your world starts to be about everything except what it is about.
And equivalency certainly is not about "better images". Another straw man from you.
And yes, diffraction softening really is the same with similar sensor resolutions and equivalent f-stop values. With above mentioned caveat.
