Re: [csswg-drafts] [selectors-4] :defined

To embellish on @annevk's statement with an example.

```html
<foo-bar></foo-bar>

<style>
  foo-bar { visibility: hidden }
  foo-bar:defined { visibility: show }
</style>
```

If a user wanted to preserve real estate but not display until element is `defined`.

@annevk does that help or hurt?
