Regarding, Node inbuilt native functions (in other works deps) that are independent of v8, continue to work in Chakra without reimplementation. Chakra shim comes into picture to map V8 C++ APIs to Chakra equivalent.
E.g. All files in https://github.com/Microsoft/node/tree/chnext/deps/chakrashi...
Disclaimer: I work for Chakra team (powering node.js)
