```ts
import { createGraph } from "jsr:@deno/graph";

const graph = await createGraph("https://deno.land/x/std/testing/asserts.ts", {
cacheInfo: alert,
});

console.log(JSON.stringify(graph, undefined, " "));
```

cacheInfo never work, it's ignored from all my use of createGraph I didn't found any way to make it work and add a CacheInfo to the ModuleGraphJson. Any hints please ?
