I think you're overlooking something. The Gen 2 Prius is classified as a mid-size hatchback. I suspect that had something to do with Toyota's decision to go with the odd shape. The extra space wasn't important to me when I bought it, but it is now.
For example, I can put down the rear seats and place an assembled bicycle inside, without removing the front wheel or lowering the seat post. I couldn't even think about doing that with my last car, an Acura Integra.

It's one of the oddest shaped hatchbacks in production, and frankly looks weird to even a hatchback lover like myself. Take a look at the front runners in the hatchback field, you'll notice big differences in aerodynamics, "sleekness", and styling. Ford Focus, VW Golf, etc... all far better looking cars than the weirdly lined Prius.
