The benefits of medium- and large-format film are still substantial for things like portraiture, landscapes, and anything that requires enormous prints. When your film or plate size is 8×10, you’re looking more "megapixels" than you can count, basically, since 35mm is scanned at perhaps 4000 horizontal pixels before you start getting no increase in detail.
This guy is obviously carrying on a love affair with large-format cameras, and has had some custom made so they can be hand-held or at the very least somewhat portable. There are several galleries and the cameras all look extremely solid. You can submit inquiries but I’m guessing these things are pretty much priceless. And I think his description of them as "small" and "lightweight" are relative to the 15-20-pound originals.
