Not sure I would call it an edge case. It's really a use case. These days, there are many developers who use the GPU for other things than plain vanilla 3D graphics. If there was ever such a thing. I'm doing a combination of scientific and practical computing, and I'm currently in the middle of the choice of whether to use DirectX or OpenGL. Portability counts, but so does simplicity. It's a very relevant question.
