I'd be worried about assuming that this is an obvious/trivial thing for implementations to do, you're effectively requiring that the internal AST representation of an implementation be entirely standardised. For example it is not possible for JSC's parser to produce an AST that exactly matches the input code -- I would expect similar problems with other implementations.
