That would seem, on first glance, to be an improvement in efficiency. Issues, however, would quickly arise when one considers that most of the 2000+ varieties of N. tabacum are and can be used for multiple purposes. Flue-cured is often considered a "cigarette" class. But many pipe blends rely heavily on flue-cured tobacco, and flue-cure-classed tobacco is often simply air-cured and used for just about anything. I use the tip leaves of Hickory Pryor--a flue-cured variety--for oscuro cigar wrapper. I have rolled puro cigars of Oriental tobacco.
I see use categorizations of an end-product in a manner similar to the "categories" that label the shelves of a bookstore. Authors have to be cognizant of how their work may be lumped. Where do you put "historical fantasy" or fiction about science that's not sci-fi? Since we're all growing our own tobacco, we can expand the traditional bounds of use classes and discover new things.
Just my thoughts.
