Polaris Icons

Few icons from the @Shopify Polaris design system

Now here's a thing for your noggin: these were designed specifically for the style guide, and not for use within Shopify itself. As in the style guide is not 100% using the styles it is guiding. Should a style guide use it's own system, or does it get to be a little different? I know my answer, but it's a thing to think about ¯\_(ツ)_/¯
