Interesting thought Piers (you often seem to have provocative ideas) ...
potentially easier to get the film in a known location. However view cameras
used flat pieces of glass. History would compel new view cameras to have as
flat as possible image planes.
Horseman, Sinar, & Canham are as flat as my metal straight edge and eye can
see.

That was my first thought, Brian, but after further contemplation, I
speculate that if the flatness of the back is not matched to the flatness of
the image produced by the lens, then any chromatic aberrations (there must
be some) would be exaggerated. In fact, I suspect that a "good" 612 back
does *not* have a perfectly flat film plane, rather one which is slightly
curved. By how much might be an interesting question.
