Can a mirrorless body make focus-shift issues a thing of the past?
I've done some research before asking here. I know from reading the manual that the EOS R, just as the 5D IV in Live View, has an Exposure Simulation feature that doesn't actually focus the camera at the selected aperture, but uses screen brightness as help in seeing what changing aperture will do to the exposure.
The Nikon D850, on the other hand, now seems to actually focus at the chosen aperture setting, and that is what the D850's Live View displays. The real thing, not a simulation.
I guess the EOS R and the 5D IV share more internals than just the sensor.
Zeiss addresses the issue a bit, but they leave Canon users hanging:

If Nikon, on a dSLR can focus at the actual aperture setting, does that eliminate, or greatly reduce, focus shift problems on lenses that are prone to it?
I'm thinking of the ef 50mm f/1.2L. Wouldn't it be great if a mirrorless could correct for focus shift even through the EVF? (Sorry if this has been asked and answered already, but I didn't find such a thread.)
