As @MaxGraey pointed out (thanks!) in #4397, `round` has different behavior from `nearest`. And it looks like the native rust implementation is still pending stabilization. Right now we duplicate the wasmtime implementation, merged in #2171. However, we definitely should switch to the rust native version when it is available.
