I find this kind of dismissiveness boring to start with.

But even beyond that, this isn't the case - the core logic for scene creation runs on the SNES and then the instruction opcodes are shipped to the expansion chip. So it's a GPU for the SNES, and a perfect analog to the SuperFX chip from which it takes its name.

A far cry from simply "using the SNES as a video adapter" as the full SNES hardware is still running the "game logic" to accept input and set up the scene.
