Compiled Deno project can't import typescript code

Does Deno compile remove its ability to import typescript code? This only work in deno run, but fails on the deno compile bynary

async function importjs(js: string, filename = "importedjs") {
  const dataUri =
    "data:text/typescript;charset=utf-8," +
    encodeURIComponent(js) +
    `//# sourceURL=${filename}.ts;`;
  const r = await import(dataUri);
  return r;
}

console.log(
  (await importjs(`export default () => "hello world" as any`)).default()
);

async function importjs(js: string, filename = "importedjs") {
  const dataUri =
    "data:text/typescript;charset=utf-8," +
    encodeURIComponent(js) +
    `//# sourceURL=${filename}.ts;`;
  const r = await import(dataUri);
  return r;
}

console.log(
  (await importjs(`export default () => "hello world" as any`)).default()
);

Yes, the compiled artifact is a slimmed down version of deno with non-critical stuff like the test runner, transpiler etc removed

would it be possible to have flags on how slim you want the copmiled binary to be? Is it feasible for a non-Rust expert to fork and maintain?

at the moment no. I don't think there are plans to add this either would love an issue on github for this though which outlines the use cases. I think right now there is nothing that tracks that
