"This is not a performance optimization or a convenience. It is the property that makes self-hosting possible. If host objects can leak into SX environments, then the spec files depend on host-specific types. If SX expressions can call host functions directly, the evaluator's behavior varies per host. Neither of those is compatible with a single specification that bootstraps to multiple targets.")
