CJS shorthand does not enable all CJS options

[tilgovi]

The documentation says that { @std/esm: "cjs" } is a shorthand for{ "@std/esm": { "esm": "js", "cjs": true }} but these result in different behavior.

Given the following file:

import { lstat } from 'fs';

Running node -r @std/esm on it results in an error with the shorthand but not with the long version:

SyntaxError: Module 'fs' does not provide an export named 'lstat'

Perhaps the first if condition at https://github.com/standard-things/esm/blob/master/src/pkg-info.js#L160 should call createCJS(true) and set cjsOptions?

Ah, thank you!
