I guess you guys never had a field camera where the plane of focus can be at an angle to match the subject, or conventionally; That's where you have to adjust the subject to suit the fixed plane of focus ( moving it in-out is not the same - but that's all you can do with modern consumer cameras, since the relationship between lens centre and sensor is 90 degrees ).
If you attempt to photograph a piano from the side, you can only get a few Keys in sharp focus (ignore iris smaller than f/8).... but by swinging the lens/sensor you can have almost all sharp. Similarly with a plate of food - getting it sharp front to back will need a very small iris, with the accompanying loss of definition.
Yes! there is a funny-lens, that attempts to do similar, but the optics are so fuzzy no-one will know what was the artist's intention...er, IMHO.
