Probably you don't know Python that well, then... Also we don't need performance parity. We just need enough performance for such a framework to not suck. Interpreting Python bytecode in Javascript already doesn't suck that much, compiling bytecode to WASM and then to native machine code would suck even less. And there are always ways to improve the performance of critical parts.
