JSC makes breaking changes to the bytecode format on a regular basis. It’s an internal implementation detail and isn’t going to be exposed to standards. Also the bytecode format has no memory safety guarantees so standardizing it wouldn’t be a great idea. It’s only trusted to obey basic VM invariants if we know that we generated it ourselves.
