In my mind the LF, MF, and miniature format designations are more about the camera body design and handling than about the film substrate.

I think of film classified by size. 120 is 120. Sheet film is sheet film. I don't think the distinctions make as much sense for the film. I have often wondered why people spend hundreds of dollars for a 6 x 12 roll film adapter when there is a perfectly usable 6 x 12 image in a 4 x 5 film holder. but my place is not to judge others.
