> if you emit Spidermonkey/Hydrogen bytecode

Hydrogen is not a bytecode, it is highlevel intermediate representation for optimizing compiler generated from AST. There is currently: 1) no frontend in V8 that accepts hydrogen in some serialized form; 2) no way to generate non-optimized (non-specialized) code from hydrogen which is quite crucial to make adaptive optimization pipeline running.
