Hey there's definitely a need for something like this. But the quantized stroke width is too limiting to make this icon set widely applicable. The ability to finely tune the icon weights, in a similar way like the weight of a variable webfont, would be truly game-changing. I'm not particularly enthusiastic about outline icons, as I feel like they go against some gestalt principles, but being able to blend shapes in with the rest of the art regardless of scale would be really powerful.
