It's important to remember that ChakraCore only currently builds on Windows, so this is only for Windows Node.js builds.
The ChakraCore roadmap [1] shows that they plan on porting the interpreter to Ubuntu, but not to Mac OS, and they don't plan on porting the JIT. So even it does go Windows + Linux, it will still be a low-performing toy on Linux.
This is vaguely interesting from a technical point of view, but doesn't seem like it'll majorly impact the future of Node.js, except maybe as something Microsoft can offer for Azure customers that choose Windows Server.
