Allow me to introduce you to Mithril (http://mithril.js.org/), the 18kB (uncompressed) virtual-dom implementation that beats React in many benchmarks.

> And because it uses the browser's built in DOM toolkit rather than a virtual one, (in theory) it should become faster whenever browser DOMs become faster.

...as will all virtual-dom implementations get faster as JS becomes faster. I would argue that there is more attention paid to JS-speed than DOM-speed because there is a server-side (among other things).
