Can Mojo be used to write trusted applications (e.g. postgres extension)
Like PL/Rust(https://tcdi.github.io/plrust/trusted-untrusted.html), would Mojo be designed in a way that it can be be run without affecting the environment(e.g. disable file system operations, network calls etc). The main use case is creating an extension like PL/Rust. It may not be a feature now but just wondering if this is in the roadmap
