A big challenge with self-hosting is memory consumption. A JavaScript implementation is tied to a realm and therefore each realm will have its own implementation. Contrast this with a C++ implementation of the same feature that can be shared across many realms. The C++ implementation is much more efficient.
If we want to get further with turning the web platform into a giant JavaScript library, we need to tackle this somehow. Has anyone been thinking about how to do this and what changes it would require from JavaScript proper? We're now at the point where we can implement platform objects in terms of JavaScript, but JavaScript loses out due to lack of efficiency.
