From LF we learn that a lense is focussed to infinity when the focal lenght is equal to the distance from film plane to lense, that´s why LF cameras have bellows and rails to move the front including lense to proper distances for diffence lenses.
Cameras without bellows have a fixed distance from film plane to lense, the flange distance. With this fixed flange we cannot adjust the camera to the lense, we have to adjust the lense to the camera and this brings much more complicated lense designs, the retrofocus fakes a shorter flange and the tele a longer by adding additional elements which are not needed when flange distance is equal to focal lenght.
So with a 16mm flange a 16mm lense will bring perfect pictures without the effort to fake a flange, Z mount will be superior to F in short or very short lenses, but this advantage isn´t given with longer lenses, look e.g. at Leica, as rangefinders they have small flange and are famous for wide angel lenses, but they didn´t even try to make teles, longest is 90 mm and maybe an experimentical 135mm or similar.
