First time reading this.

On one hand it looks neat. This is something i expected browsers to be able to do since i noticed that Mozilla (pre-Firefox) implemented <blink> (or <marquee>?) in JavaScript.

On the other hand it looks like it'll become much harder for JavaScript-less environments to extract data from web-pages as now an article on a news site could be something like <news-article id="23848923"> and the JavaScript side will do the rest.

But being able to do something like <my-fancy-button caption="Go To Google" target="http://google.com/"> that in the background creates all the canvases and such needed will be neat.

This is already the case on a lot of sites, just not standardized. With the standard you could sandbox the javascript or maybe implement specific parsing for the most common web components.
