More likely, knowing our friendly neighborhood JIT-coders, Maps which only contain string keys will be optimized under the hood.

That’s a good point. And __proto__ being just another property helps tremendously.
However, not having methods seems unfortunate. It would be nice for Dicts to look like Maps with only string keys, but with get(), set() and has() being optimized under the hood. But maybe that’s too much effort.
