Seems using esmo solves the issue though I do get the experimental loader warning which I'm hoping we can supress?

❯ esmo .\bin\test.ts
(node:40156) ExperimentalWarning: --experimental-loader is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
(node:40156) DeprecationWarning: Obsolete loader hook(s) supplied and will be ignored: getFormat, transformSource

Actually this doesn't fix the issue since I now can't mock dependencies since everything is being imported as an ES module.

   ES Modules cannot be stubbed

Seems more like an issue to be reported with Esmo. Japa itself is not registering any loader hooks with Node.js. https://github.com/antfu/esno/issues/21
