Yes, we implement the Stage 1 proposal almost in full (except for cross-realm leakage which we still allow).

I've determined two benefits in aligning with SM and moving accessors to Function.prototype:
  * that greatly simplified our JSFunction overrides;
  * a userland function with own non-configurable properties was problematic to use as [[ProxyTarget]].
