I would personally have just waited for Node.js to backport the feature. Seems like a bit of waste of time to add an option that will soon be moot. But the work is already done, so why not.

So looks like the node: scheme / prefix was backported to Node.js 14.13.1 / 12.20.0 🎉

https://nodejs.org/api/esm.html -> link "node: Imports" (links with anchors don't scroll properly right now)

Ah, maybe require / CommonJS support is not quite there yet:

In Node 16 require('node:fs') works, but it looks like it still doesn't in 14.17.0.
