@nolan@toot.cafe There’s a number of web components folks involved in MWG (myself included), so I don’t think it’s intentional that custom elements might be snubbed in the output. We could probably do a better job of mentioning good opportunities to use them as well as providing stronger guidance in favour of using them. Some of the newer guidance categories (e.g. `guides/ui-components`) are a good fit for doing just that. (Opinion: completely my own) In case you don’t know, the fuller source for the project is here: https://github.com/GoogleChrome/modern-web-guidance-src
