Seems as no one outside of 35mm FF players seem to give it a second

That's not true. Do a search over at Photo dot net. Photographers have always cared about what f-stop is needed to get a certain depth of field, which is very much dependent on format size. There wouldn't have been an f/64 club for 35mm photography, right? The cultural imperialism and frequently misleading wording (eg calling fast lenses "effectively slow") are the new parts of a topic which has been of practical interest for decades.
