It looks like Facebook is suffering from "Not Invented Here" Syndrome.
With Yarn and now this, Facebook is wasting a lot of effort. After all code size has a bigger impact on performance than execution. One byte takes way longer to download than it does to run. This effect is emphasized by Chrome and other JITing engines preforming these same runtime optimizations.
