Re: [WICG/webcomponents] Why can't the registry enumerate the custom elements? (#775)

What is your actual use case? Why do you want to enumerate custom elements?

If you're doing this for some kind of debugging purposes, you can just put a Proxy around registry, right?
```
window.customElements = new Proxy(window.customElements, {...})
```
