Tried your commit and it looks like the performance looks the same and the wasm binary works for me! If it's preferable to everyone I'm okay with either pulling this here or maybe it's better for @QuantumSegfault  to open an alternative PR with this approach (and close this one) as the code is much different than what is in my PR (I would prefer to do it that way).
