Ah, interesting. Yeah, that sounds like they're just planning to stop optimizing V8 or something, since you can clearly do better than that. The type inference branch of Jaegermonkey is already faster than V8+Crankshaft on compute-heavy (as opposed to GC-heavy, where V8's better garbage collector gives it a big edge) workloads, and that's without LICM or smart register allocation or any of the other global optimizations that are still coming online.

It's unfortunate that Google is deciding to focus on Native Client, with its portability issues, if that's what's going on.
