Using inject with target=es6 -> export error

[Le0Developer]

I'm trying to use inject to shim some functions while targeting es6, but I am getting the following error due to the export { fn as name } syntax:
Using a string as a module namespace identifier name is not supported in the configured target environment ("es2015")

Playground reproduction using the process.cwd example shim from the docs. Removing target=es6 from the compiler options makes it build as expected.

I've been trying alternatives (such as export default { name: fn }, module.exports = { name: fn }) but using them causes esbuild to not use the shim. (export let name = fn does work, however the name cannot contain dots in that case).

Any advice would be appreciated 🙏

There was a way to inject a.b like things with --define:process.cwd=__process_cwd.

This feels more like a work-around than a proper solution I'm looking for, as it requires me to duplicate all shims into the build options.
