We're currently using Font Awesome v4 (https://fontawesome.com/v4.7.0/), which is only available as a fonts + CSS distribution. We only use a few of the icons, yet the fonts+CSS implementation means having to download all of them regardless (the fonts vary between 77KB and 444KB depending on file type used by that browser, and the CSS is 37KB). Font Awesome 5 has been out for a while now, and offers a superior SVG + JS solution that supports tree shaking. (The reason we haven't had a Renovate bot PR for the upgrade is that they've changed the package name for the new version.) In addition, we currently use a mixture of plain Font Awesome and react-fontawesome, and so to simplify things we should consolidate on the latter rather than having the bundle-size and "things to learn" overhead of using both.
