Note that it looks like SIMPLE_FLOAT merely makes an optimization which allows a GL_ZERO factor to cause a 0 to result... sometimes. But it could be enough here. If an infinity or NaN makes it into a dest buffer, without this it will ruin any future blending done, even if there's an attempt to override the destination value.
